Making Map Layouts
Before Getting StartedAll the tools you need to create simple or complex maps and posters are found inboth the Display and Page Layout modes of the Display process. The ability toprecisely position objects on the page is part of any layout package, but the TNTproducts also provide the ability to add scale bars, map grids, legends, andannotation text as part of the powerful map and poster layout features found inthe visualization process.
Prerequisite Skills This booklet assumes you have completed the exercises inDisplaying Geospatial Data and Basic TNT Concepts tutorials. The exercises inthose booklets show you how to select and view raster, vector, CAD, shape, TIN,and database objects stored in Project Files. You should know how zoom, pan,and enhance display objects. Please be sure you remember how to add and removelayers from a multilayer view. You should also know how to set up and select yourprinter. This booklet does not present these basic skills again. Please consultDisplaying Geospatial Data and Basic TNT Concepts for any review you need.
Sample Data The exercises presented in this booklet use sample data distributedwith the TNT products. If you do not have access to a TNT products DVD, youcan download the data from MicroImages’ web site. The exercises in this bookletuse objects from all Project Files in the MAPLO folder of DATA. The objects in theTOWNS Project File in the CARTOSCR folder are also used. Be sure to make a read/writecopy of these files on your local drive.
More Documentation This booklet is intended only as an introduction to thefunctions in Page Layout. Consult the reference materials at microimages.comand the Printing tutorial for more information.
TNTmips® and TNTmips Free TNTmips comes in three versions: TNTmips Pro,TNTmips Basic, and TNTmips Free. This booklet refers to all versions as“TNTmips.” If you did not purchase the professional version (which requires asoftware license key) or TNTmips Basic (which is locked to an individualmachine), TNTmips operates in the TNTmips Free mode, which limits the size ofyour project materials. Most exercises in this booklet can be completed inTNTmips Free using the sample geodata provided.
It may be difficult to identify the important points in some illustrations without acolor copy of this booklet. You can print or read this booklet in color fromMicroImages’ web site. The web site is also your source of the newest tutorialbooklets on other topics. You can download an installation guide, sampledata, and the latest version of TNTmips Free.

Making Map Layouts
Welcome to Making Map LayoutsLaying out maps and posters generally requires youto assemble and arrange several objects for the dis-play screen or on a page. These objects may all bein a single georeferenced group with map grids, butyou may additionally require scale bars, annotationtext, map grids, legends, and other objects such as anorth arrow or your company logo. The ability tocreate map grids, scale bars, legends, and annotationtext is an integral part of TNTmips’ Display and PageLayout features.
All of the tools and features in the Display process areavailable for display and page layouts, includinginsertion of sketch layers and 3D groups. Displaylayouts let you arrange objects relative to each otherin the view window while page layouts add theconcept of positioning relative to a page, which isnecessary for printing. Any layout you create can besaved for further refinement or as a template to bereused in a series of maps.
Georeference is the basis for positioning layers in thesame group and for the relative sizing of separategroups. When objects are georeferenced, you canprint to or display at a specified map scale, which canbe reflected in a scale bar and explicitly designatedin text if desired. Objects that are not georeferenced,such as logos and text, are placed in separate groupsso they can be sized and positioned independently.Some layouts may contain no georeferenced compo-nents, such as layouts made of screen captures andtext for inclusion in a report.
The full layout capabilities of TNTmips are avail-able in TNTmips Free, however in the latter you arerestricted to a maximum layout size of 11" x 17"(tabloid size page). The professional version ofTNTmips supports printing on a variety of largescale printers (paper sizes up to as large as currenttechnology allows) and printing over multiple pages.Support for dithered color printing up to 11" x 17"is included in the base price of TNTmips Pro.

Vocabulary: Most printerscannot print up to the edgeof the paper. The area thatcannot be printed is calledthe unprintable margin.The size of the unprintablemargin varies from oneprinter model to the next.
Pages 4–10 describepositioning multiple groupson a page, adding mapgrids, and printing. Onpages 11–18 you develop amore complex layout thatincludes annotation text, alegend, logo, north arrow,and scale bars in addition tomultiple layers in ageoreferenced group with amap grid. The rest of thebooklet provides informationabout development of mapsin a series, templates,legend types, databases inlayouts, sizing and scaleissues, rendering to variousformats, and map scale-controlled visibility.

select Top to Top fromthe option menu in theVertical panel, and clickon [Redraw]
Red lines indicateunprintable margins.
Keep this layout openthrough the exercise on p. 8.
Automatic group placement in page layouts differsfrom that in display layouts. Groups are automati-cally tiled in a display layout and have no specificattachments. All groups added to a page layout havean initial group attachment that centers them on thepage. Customized group placement is establishedwith the Placement tool or in the Group Settingswindow, which you open by clicking on the Settingsicon found in the group icon row of the DisplayManager or with the Placement tool. The parametersset apply to the currently active group. You change
the group you aremaking settingsfor by changingthe active group.
You can changegroup names bytyping a newname in the Group
Settings window, but in this example there are justtwo groups with Group 1 at the top of the page andGroup 2 at the bottom, so we’ll leave the defaultnames.
The map scale at which your layout is printed is setin the At Scale field at the lower right of the GroupSettings window. The value in this field is the sameas that in the Map Scale field of the Page Setupwindow; a change made to one of these fields isupdated to the other.

Making Map Layouts
Setting Group ProjectionsThe default group orientation uses the object coordi-nates of the first (bottom) layer in the group. If youwant the group orientation to be derived from mapcoordinates, you need to set the Auto-Match featureto None and choose a projection for use in orienta-tion. Once you choose a group projection, the layersin the group may be reoriented according to theprojection. The selected projection and the geom-etry of the objects selected for display determinewhether a Projection Upright orientation is notice-ably different from an Object Upright orientation.
STEPS
Note: when rasters arerotated in a layout, they tendto slow the printing process.Within the size constraintsof TNTmips Free or whenrotated to 90°, 180°, or270°, the effect is notsignificant. However, whenprinting large rasters, youmay shorten the printingtime by rotating and savingthe raster (Raster /Resample and Reproject/Automatic) prior to printing.Then substitute the rotatedraster for the original in thelayout.
with Group 1 active, clickon the Projection tab inthe Group Settings win-dow and choose Noneon the Auto-Match optionbutton, then click on [Pro-jection]

Making Map Layouts
Adding Map GridsA map grid may contain one or more of the follow-ing components: grid lines, neatline, border, inte-rior/exterior tick marks, and coordinate labels. Wewill use all except interior tick marks. You can setthe color and size independently for each of these.You can also set the font and style for coordinates.
Any map grid added comes up by default in theselected group projection. You can always changethis projection, either for the group as a whole or forthe map grid. You can also overlay multiple mapgrids in different projections on a single group.
The default map grid colors are a medium gray sothey have a fair chance of showing up over mostimages and backgrounds. Let’s set the neatlinecolor to blue and all others to black.
with Group 1 active,click on the AddMap Grid icon
check that the Refer-ence System is UnitedStates State Plane 1927[NAD27/SPCS27 Ne-braska North Zone (m)]and the units are meters

Printing a LayoutFor most applications you would print a single largeimage with two different map grids overlaid ratherthan two separate groups with their own map grids aswe have here. The point of the exercise, however, isnot only adding map grids, but also group position-ing, projection, and orientation.
We are now ready to print this layout. The defaultprinter is always the last selected printer so youshould be set to go from your printing exercise in theDisplaying Geospatial Data tutorial. It is always agood idea to check your page setup when you haven’tprinted for a while unless you know no one else usesyour computer.
STEPS with Group 2 active,
click on the AddMap Grid icon
check that the Refer-ence System is Latitude/ Longitude (NAD27/Geographic) on both theExtents and Intervalpanels with a N-S and E-W interval of 0 01 00.00
check that the settingsmade in steps 4–8 on theprevious page have beenmaintained
click on [OK], thenRedraw
The optimal dither pattern willvary from printer to printer. Youmay even wish to let Windows dothe dithering. The selected ditherpattern is the one I prefer forcolor raster images on myprinter. Be sure to leave theNon-Raster Dither Pattern set toVector Pattern.
choose Print from theDisplay menu in the Dis-play Manager window
verify that the printerModel and Destinationare as intended
click on the Dithering taband set the Raster DitherPattern to Jarvis-Judice-Ninke (or let Windowsdo the dithering)

repeat for the other tickmarks over the butte
save your layout for usein the exercise on p.44
TNTmips provides the ability to toggle between anytwo colors for interior map grid tick marks. Use ofthis feature creates greater visibility of map grid tick
marks over the entire map area whenthere is considerable variation inbrightness over the underlying image
or vector. You choose a primary color, which isinitially assigned to all interior tick marks, and asecondary color, which can be assigned to indi-vidual tick marks as shown in this exercise. Interiorborder tick color can also be toggled.
You toggle tick mark color using the Select tool inthe GeoToolbox, not the Select tool in the Viewwindow. This right mouse button menu choice isalso available when other GeoToolbox tools areactive. When you right-click with the Select tool, amenu with a single choice pops up. If you activelychoose Toggle Grid Tick Color from the right mousebutton menu, the single, closest interior tick mark orinternal border tick from all the map grid layers ischanged to the secondary color. If you subsequentlychange the secondary tick mark color, the color ofthe tick marks assigned to the secondary color willalso change when the layout is redrawn just as fortick marks drawn in the primary color. You can, ofcourse, also toggle a tick mark back to the primarycolor.

Display Scale 1:240000 1:120000 1:60000 1:60000
The point of using a map layout product, such asTNTmips, instead of a page layout product likeAdobe® PageMaker® or Microsoft® Publisher, is thata map layout product uses georeference informationto determine accurate map scales for printing andprecise geographic overlay of a variety of objecttypes. However, often not all components of a mapor other layout are georeferenced (for example,annotation text, legends, and company logos). Thesize for such components must be set when design-ing a layout, and that size needs to be either absolute(unchanging) or relative to some map scale.
You set how to determine size for text, legends, linepatterns, symbols, and some scale bar parameters.Map scale enters into displayed sizes, so your choicealso determines if the size changes as you zoom inand out. How to set the size for ungeoreferencedobjects like logos and text is discussed in the Rela-tive Group Zoom exercise.

Making Map Layouts
Symbols with Fixed Ground DimensionsYou may want to design a symbol or line pattern sothat it is always the same size or width on the groundregardless of the scale of your layout or the resolu-tion of your data. For example, a four lane dividedhighway should have the same width on the groundwhether displayed over a raster with 1-meter or 10-meter cell size, and a symbol for a radar reflector thatmeasures ten feet across should represent ten feetwhether displayed at 1:60000 or 1:120000.
Fixed ground dimensions are not a property of thesymbol or line pattern—they are a property of thestyle. Achieving such real-world sizes across mapscales requires that the At Scale option be set to User-Defined. You could theoretically set the symbol sizeor line width at a map scale of 1:1, which wouldeliminate scaling calculations, but the Style Editor
attempts to display thesample at the requestedabsolute dimensions, anda 10-meter symbol far ex-ceeds the availablesample area. A number ofreasonable size examples
are provided below to assist you in setting your ownmap scales.
The symbology used inthis exercise is not sig-nificant, but the resultsare. The measurementsshown are the same forobjects whose extentsvary by approximatelyten-fold.
at 1:12000, 1" = 1000 feetat 1:120000, 1" = 10000 feetat 1:1200, 1" = 100 feet

Now we’re going to create a fairly typical image mapusing a central large raster with a map grid and CADoverlays, a legend, scale bars, north arrow, companylogo, and annotation text. Let’s start the map withthe largest group, which contains a raster and threeCAD layers.
We’ll add the map grid next since it will change thesize of the group. The default projection for a mapgrid is obtained from the georeference selected in theLayer Controls for the first layer, which happens tobe Universal Transverse Mercator (UTM) for theraster layer in this layout. We’ll change this toLatitude / Longitude.
Unless theextents are asspecified here,the neatline willnot be at theraster’s edge.

The icon for adding a text layer is on the mainDisplay Manager toolbar because text must be in aseparate group for sizing and positioning. The bestchoice of group attachment options depends on avariety of factors such as whether you want the group
to follow movements of an-other group and whether thelayout will be used again at a
different map scale.Not all printers havesymmetrical margins,so horizontal center-ing is best achievedby attaching to thepage. You can posi-tion objects at theedge of the printablearea by attachingthem to the margin.
An outline of the group extents appears when youswitch to the Placement tool so you can drag a groupto a new position on the page. The cursor is the crossarrows shape for repositioning. The cursor shapes(and functions) used for resizing elastic boxes areinactive while the Lock toggle next to the RelativeZoom field is on. This lock prevents inadvertentchange of the group’s map scale relative to thelayout scale and other groups, so that the groupprints at the map scale you expect.
* You could use the default horizontal attachments for thisexercise, but this attachment is needed when you get to p. 39.

Using the Layout Placement ToolThe Layout Placement tool provides a graphic meansof visualizing and changing the position and attach-ment of all groups in a layout. You can make a groupthe active group by clicking on it. The informationin the Group Settings window is updated when theactive group is changed and the group becomeseligible for changes in position and attachment. Usethe Placement tool and the Group Settings windowtogether to get the results you want.
Changing group attachments works differently withthe Placement tool than in the Group Settings win-dow. If you change what a group is attached to in theGroup Settings window, the values in the Spacingfields remain the same. If you change the attachmentwith the Placement tool, the group remains in thesame position on the page and the spacing values arerecalculated to reflect its distance from the newattachment group.
There are three viewing modes: normal, wireframe,and solid. In the normal mode, all layers are drawnand the Placement tool elements are added. Reposi-tioning is easy in this mode, but it is sometimesdifficult to see the attachment arrows. Drawing isfaster in the wireframe and solid modes. You choosethe viewing mode from the right mouse button menu,which also has a Lock Scale toggle if over a group.

click on [OK] in the ScaleBar Layer Controls
The vertical spacing for the final position of Group1 will be a negative number (indicating it is abovethe point of attachment) that varies with yourprinter’s printable area. The group’s position canalso be adjusted by entering a number directly in theSpacing field for horizontal or vertical attachment.Pressing <enter> over the layout when the Place-ment tool is active initiates a redraw.
Maps often contain more than one scale bar toprovide scale using different units. When multiplescale bars are included, they are generally stackedvertically with the longest scale bar at the top. Thelength of a scale bar is determined by the map scaleof the layout and the relative zoom of the group. Ifyou are providing scale for an enlarged inset, youneed to be sure the relative zoom of the scale bargroup is the same as that of the inset (see the laterexercise on Relative Zoom). Because width is thedimension opposite to length, the width set is thethickness of the scale bar.
The number of minor divisions must divide evenly into the

length of the majordivisions (you canhave 5 but not 6minor divisions ifthe length of a majordivision is 0.5 miles).
You now have a scale bar,which is the active group,centered on the page.
page 15
Making Map Layouts
Multiple Scale Bars and PositioningOnce you have added one scale bar, you just need tochange the parameters in the Map Units panel,namely the units and length, to add other matchingscale bars to the layout. Settings in other panelsshould remain the same.
Note that you can change group names before or afterestablishing attachments; the attachment informa-tion is updated whenever a name is changed. Attach-ing the scale bars to each other and then to the imagemap (Group 1) lets you establish uniform spacingbetween the scale bars, and sets it so subsequentadjustments to the image map position bring alongthe scale bars with the current spacing maintained.Thus, if you later decide you want to move the imagecloser to or further from the heading text, the scalebars will also move provided you make the positionadjustments to Group 1. When you change to adifferent tool, such as the zoom box, the View isredrawn.

Adding a Logo and North ArrowMap layouts generally contain one or more compo-nents that are not georeferenced. In addition toannotation text and legends, which are sized relativeto some map scale when added, there may be a northarrow and logo or other strictly graphic components.All such components must be placed in separategroups so they can be sized independently.

Adding a Legend and Descriptive Text
This image map was generated usingthe interactive Page Layout processin TNTmips from MicroImages, Inc., 206S. 13th Street, Lincoln, NE 68508-2010,(402)477-9554. The layout was printedon a (name of your printer).
A line legend object has been prepared for your usein this layout. This legend includes only the waterrelated line features; road lines are not included.You create your own vector and raster legends inlater exercises.
Text entered as part of a layout is saved in the layoutp r o p e r t i e s ,which elimi-nates the need tokeep track of thetext separately.You can alsoopen a text file to supply the text. You can edit textafter it is entered by opening the layer controls andtyping in the changes. You do not need to press<enter> at the endof a line when WordWrap is turned onin the AdvancedSettings unless youwant to force a line break at a particular location.You can elect to justify (align on left and right) a textblock if Word Wrap is turned on.

Additional Clipping OptionsGroups can be clipped a number of different ways inthe TNT products. Clipping is done on a group bygroup basis. Not all clipping options are manuallyset as in the previous exercise. There is a toggle onthe Projection tabbed panel of the Group Settingswindow that is active as long as the Auto-Matchoption on the same panel is set to a choice other thanNone. When this Clip to Auto-Matched Layer toggleis on, the Clipping tab is inactive and the extents ofthe layer used for auto-matching are used for clip-ping. You could use this method to achieve the sameresults as in the previous exercise without having toenter geographic coordinates.
You have the option of clipping or not clipping asketch layer when the group that contains it is clipped.This setting is found in the GeoToolboxon the Op-tions/Sketch menu (Clip Sketch If Group Is Clippedtoggle). When sketch layers are used as annotation,you probably do not want them clipped with thegroup. This toggle is off by default.
There is also a Use geographically-attached groupclipping option on the Clipping tabbed panel of theGroup Settings window. This option lets you use thesame clipping settings as the group to which theactive group is geographically attached. For moreinformation on geographic attachment, see the laterexerise entitled Attach Groups by Georeference .

Placement Tool Hot and Modifier KeysThe Layout Placement tool has a number of key-board shorcuts to make your layout manipulationsquicker. These keys are only active when the Viewwindow has focus. Both the spacebar and the <en-ter> (or <return>) key redraw the view when thePlacement tool is active. The arrow keys work tonudge the active group and all groups attached to it.
Holding down the <shift> key while dragging orusing the arrow keys to move a group that hasattachments from another group will move the groupyou are dragging without repositioning the groupsattached to it. The unmodified dragging action(<shift> key not pressed) repositions the group youare dragging and all the groups attached to it.
The zoom control hot keys are availablle when usingthe Placement tool just as they are for other Displayactivities. Choose the desired option from theHotKeys menu in the View window. Note that thespacebar and arrow key functions are different thanlisted on the menu when the Layout Placement toolis active.
The View window automatically gets focus whendoing any dragging action because you must clickon the window. Check that the View window hasfocus if you are using hot keys and do not get theintended action.

Maps in a Series: Same Paper SizeYou may be doing production work in which youwant to make a series of maps that use roughly thesame layout. The selections you make when settingtext sizes and line widths determine how easy it is toreuse a layout. In general, the At Design Scalesettings are best suited for a series of maps designedfor the same paper size. Such maps may containdifferent depictions of the same ground area or maybe of a different location at the same map scale.Templates can easily prompt you for replacementobjects for such a map series (see the next twoexercises). This exercise describes how to alter alayout for a different location at a different map scalebecause it is a somewhat more complex problem.
You can “reuse” a map grid from one layout toanother that covers a different geographic area byopening the Map Grid Layer Controls and updatingthe extents of the map grid without altering otherparameters. If the map scale is significantly differ-ent, you may also want to change the grid interval.
The width and text size for scale bars is alwaysrelative to a map scale, so you need to change thisscale to the new layout scale to keep the same textsize and width. The length automatically changes tobe correct at the new layout scale, however, you maywant to change the assigned length of the scale bars.You also need to select the groups containing thelogo and north arrow and enter the desired height (orwidth).
The text groups may needto have the text changedto correctly identify thenew map; Millington SWshould be changed toCrow Butte in this ex-ample. Some text layers,such as the one at the lowerright, may apply to all lay-outs without editing.

Maps in a Series: Different Paper SizesThe maximum printable area in TNTmips Free andBasic is tabloid size (11" x 17"), which is sufficientlylarger than letter size to illustrate the effect of chang-ing paper size on a layout. You do not actually haveto have the printer to select it (if choosing modelswith the Printer option toggled on).
Setting text and legend layers relative to somedefined map scale means that they change size as themap scale changes, which is what you want tohappen if you’re also changing paper size when youchange map scale. As mentioned on the previouspage, scale bar size specifications (width and linethickness) can only be relative to a specified mapscale. The text size can be relative to either a user-defined or the design map scale. The length of scalebars always adjusts automatically when the mapscale of the layout changes.

Display icon, andselect the Millington lay-out saved on p. 19
click on the GroupSettings icon for theNorth Arrow group
click on the Special tab,then turn on the Savelayers to template “as-is”toggle
Layout templates are designed for use with maps ina series at the same layout scale and the same papersize. You could, however, have used a template forthe last exercise, but the idea is to teach you a varietyof methods for modifying layouts.
You need to do some preparation work with yourlayout before saving it as a template or you will beprompted for the contents of all replaceable groupsin the layout. There is a single control that deter-mines whether or not you are promptedfor new group contents when a tem-plate is opened. This control is lo-cated on the Special panel of theGroup Settings window. You need toturn on this toggle for each group thatwill be a constant feature in your mapseries, such as the North arrow and logo.
Scale bars are one layer type for which this toggledoes not need to be set—they will be the same, unlessyou change the map scale, and then they are auto-matically adjusted. Legends also remain the samewithout any special settings. If the samelegend does not apply to the new map,you will need to change the legend (seeexercise on page 25). With multi-objectlegends, as long as the layer namesremain the same, the legend will beupdated to reflect the new objects. Thelayer name can be the file and objectname, the object name, or the object’sdescription. The one you select needsto be consistent across objects if youwant the legend to apply to the replace-ment objects.
Groups with map grids are handled specially. Al-though you are prompted for replacement layers, themap grid remains and is automatically adjusted tothe extents of the new group contents.

zoom up on the upperleft corner and note themap coordinates havebeen changed
One of the features of templates is to prompt you fornew group clipping extents if clipping was on in thelayout from which the template was saved. If yourecall, you had entered the extents for the MillingtonSW raster and applied clipping to Group 1. In theexercise on page 21 in which you manually updatethe layout, turning off clipping was included as oneof the steps before the new layout was drawn. Ifclipping to the previous coordinates was still ap-plied to the new Group 1, the image map would notbe drawn since it is completely outside the clippingrectangle. Thus, if you are using a template to makea series of maps of the same ground area with differ-ent overlays clipped to specific extents, you willhave to reset the extents for clipping the group whenthe template is loaded. The clipping extents at thetime the template was saved are still listed on theclipping panel.
It is possible in a map series that the samelegend would apply to all the maps, but thatis not the case between the Millington andSt. Marys City quarter quads. In the nextexercise, you will learn how to make a newlegend that does apply to this map.
Note: You can also createmaps in a series using anSML script. This approachis described in the Printingbooklet.

Interactive Legend DesignMulti-object legends let you combine legend infor-mation for multiple objects and/or multiple elementtypes in a single legend. They also offer features notavailable in other legend types, such as interactiveplacement of legend components and the availabil-ity of frames and shadows. You will create a legendfor the points, lines, and polygons from a singlevector object. The method for adding additionalelement types or objects to the legend is exactly thesame as that for adding the first. All new items in the
legend are initially placed in a singlecolumn. Items are selected for moving orediting by clicking on them. Clickingon an item then shift-clicking on a sec-ond item will select the items you clickedon and all items in between. Holding thecontrol key while clicking lets you makemultiple, noncontinuous selections.
Another feature that distinguishes multi-object legends from the other legend
types is they are storedas part of the layout,like scroll bars andtext, rather than asseparate objects. Thelegend is saved to thelayout when you clickon the OK button inthe Legend LayerControls. You canedit the legend byclicking on the
group’s legendicon.

If your printable area issmaller than that of theprinter selected for theillustration, you may findthat the legend is toolarge to fit in the remain-ing space. Just click onthe Legend icon for thegroup and reduce thesize of samples and textas needed. See theCartoScripts booklet forhow to get CartoScriptsamples into legends.
Multi-object legends have two default text styles:Normal and Heading. Normal is used for labels andHeading is the default for added text. You can,however, change these assignments in the Propertieswindow for the selected item. You can also changethe font, size, and style of both text types using theEdit Text Style button at the top of the Legend LayerControls. Additional text styles can be added forcomplex legends. A heading can be repositionedand edited like any other item in a legend.
You can control the amount of space between legenditems using the Offset values in the Properties win-dow. All items start out equally spaced, but this maybe inadvertently changed while dragging. Simplyselect all items that you want to have the samespacing, right-click to open the Properties windowand enter the desired value for the top and left offset.The top offset applies to the distance from the itemor guide immediately above, so you may want a topoffset of zero for the top item in each column. Youcan also change the order of items by dragging, and
spacing willautomaticallybe adjusted toaccomoda tethe change.
* Groups that can have onlyone layer, such as legends,scale bars, and text, havelimited functions available inthe Group Settings window,and the icon that opens theGroup Settings window is theLayout Placement icon.

Mattes with Legends and Other GroupsA legend frame, such as that set up in the previousexercise, is a simple example of a matte, or back-ground layer. Mattes can be used for decorativeeffect with legends or any other group type and forentire layouts as well. A legend frame is limited toa solid border with a solid fill and a solid color dropshadow. Instead of setting frame parameters for alegend in the Legend Layer Controls, you can choosea matte for the legend group if you want moreelaborate effects. Mattes provide gradient and radialfills using any two colors and the color spread typeyou specify. You can also specify solid fills. Thereare nine predefined border styles for mattes (solid,double, inset, outset, etched in, etched out, groove,ridge, and rounded), and CartoScripts can be used tocreate more ornate borders. You can choose a blendeddrop shadow for mattes in addition to the solid dropshadow available for frames.
Many solid colors are too dark for use as a mattebackground. You can lighten any color if youinclude transparency and the matte is part of a pagelayout to be printed on white paper, it will lighten thecolor considerably. Remember that mattes can be
used for any group andthat not all componentsof a matte need to be used.

The raster theme mapping feature automaticallygenerates interval categories from the cell values ofraster objects. The Raster Theme Map Controls letyou set the number of intervals you want, the distri-bution type to use in determining the intervals, andthe colors you want.
The raster theme map legend is automatically se-lected for you when you create a raster theme map.This legend will be used in the View window if youhave the Show Legend option turned on. In theinterest of space, you may want to choose an imagesample or thumb-nail for the legendeven if it is thememapped. However,the legend type youget for a raster whenadding a multi-ob-ject legend is deter-mined by the typeof legend selectedon the Legendtabbed panel of theRaster Layer Con-trols. You will notget the resultsshown in this exer-cise unless youleave the LegendType in the RasterLayer Controls setto Raster ThemeMap Ranges. If youwant to add a leg-end for the raster tothe page layout,saving space in thesidebar legend isnot recommended.

in the Group Settingswindow with theElevScale group active,set the Horizontal at-tachment to Group 1[Left to Right] with anOffset of 0.1" and Verti-cal attachment to Group1 [Top to Top]
Color scale legends are most appropriate for quan-titative data with a continuous spread color map.Because the color map value often does not reflectthe real world value it represents, you need to enterthe color map values you want labeled and the labeltext you want. We are going to have five labels suchthat the elevations end in either a five or zero. Youcan click on the Auto button and have the processgenerate the cell values and associated real worldvalues over the range you enter. However thesevalues are not likely to be multiples of five or ten.You need to enter units if you want them with theauto-generated values. You can use the procedureon the preceding page for a color scale legend butyou get only two labels. These labels are theunadjusted highest and lowest cell values. Somecontrols for additional labels are provided on theLegend panel of the Raster Layer Controls.
If you change theorder of thesevalues to 1376–1045, you will getthe highest valuesat the top of thelegend.

We are going to modify the layout just created to adda group that enlarges a portion of the raster alreadyincluded. The Relative Zoom field in the GroupSettings window should be used only to achieve thiskind of effect or when mixing groups with andwithout georeferencing. The At Scale field in thelower right of the Group Settings window sets themap scale for relative sizing and printing. The mapscale for printing can also be set in Page Setup.
You alter the group zoom when the Placement toolis active if you use any resizing functions with theRelative Zoom Lock button off. Any scale bars inthe layout then do not accurately portray the grounddistance of objects in groups with a Relative Zoomother than 1.0 unless the Relative Zoom of the scalebar group has been changed to match.
Note that the TIN object in Group 2 is being dis-played directly as contours rather than as the moretraditional triangles.You may want toopen the layer con-trols for this object tosee the settings used.

When you have groups at different map scales on thesame page, it is nice to provide a scale bar for eachand perhaps text that identifies the map scale.
The area that is enlarged in this layout is identifiedwith a box outline positioned in the larger image.Here it was added as a CAD object, but it can also becreated in the Display process using the Sketch tool.Lines connecting the upper left and lower rightcorners of the box and its enlargement can also beadded with the Sketch tool. Such cross-group con-
nections in layoutswork best when thegroups are attached tothe page or margin sotheir position does notshift when group ex-tents are redefined by
the addition of the sketch layer. (A sketch layer isadded to the active group and obtains its georefer-ence from that group.)
Just as you don’t want to change a group’s RelativeZoom unless you specifically intend to have groupsat different scales on a page, you don’t want tochange the values in the Height and Width fields in
the Group Settings win-dow. Changing thesefields also changes theRelative Zoom.
You could easilyinclude text groups toprovide the map scaleof the two images(“Scale = 1:80000” forGroup 1 and “Scale =1:40000” for Group 2).

Advanced Text FeaturesThe TNT products give you complete control overthe text styles that appear in your legends and layout.You can adjust the boldness, italic angle, enhancedthickness, stroke width (outline text and underline),underline offset, shadow offset, and shadow angle.The two angle settings are expressed in degrees andall other settings as a percentage of the ascenderheight. Using a percentage of the height keeps theweight of the text constant as you zoom in and out orchange point size (provides scalability).
With Word Wrap turnedon, the text flows to thenext line in the Text LayerControls window. Thetext flow will be differentthan the way the text flowson the page unless thewindow width is the sameas the block width. Whentext is drawn at the blockwidth specified in the layout, word wrap has to pickthe best place to break a line regardless of the textalignment chosen. Using word wrap means you needto use the <return> or <enter> key only at the end ofa paragraph. Word wrap will break a line at a space,tab, or hyphen. You can manually insert a hyphen ifyou think it would improve the appearance of a line.Generally, you do not want to turn on Word Wrap forsingle lines of text, such as headings, because theymay inadvertently wrap onto a second line.
All of the text settings and advanced options applyequally to selected text in text layers and legend textexcept that word wrap is always on in multi-objectlegends and the block width is not defined by a field,but by the position of a vertical guide.
STEPS
open the layout youworked with on p.26–28
click on the Text icon forthe SE Harlan, SW group
highlight the text andchange the style toEnhanced, changethe Foreground Colorto yellow and the Back-ground Color to blue,click [OK], and redraw
note the appearance andwidth of the text, repeatstep 2, highlight the text,click on the Text Styleicon then on [AdvancedSettings], change theEnhanced Thickness to10%, click [OK], redraw,and note the text’s ap-pearance and width
repeat steps 2–4 and tryother text style modifica-tions so you understandwhat the advanced op-tions do
Note: Changes you makein the Advanced Optionswindow are retained for thenext time you add a textlayer. The Clip Distanceoption applies to vectorswith labeled elements thathave the “clip under“ optionturned on. If you want toreturn to the initial defaultvalues, they are shown inthe window above.

Using the Character Map FeatureYou can insert special characters from any font youhave installed on your machine. You may know theinput entry codes to type directly from the keyboardfor some of these characters, but the TNT products
provide a graphical interfacefor you to select and insert allspecial characters in the cur-rently selected font. The Char-acter Map window also pro-vides the input entry code forthese characters so that you
can learn them and type them directly from thekeyboard if used often.
You can also use the Charac-ter Map to assist with textentry when editing databasefields. Your selected inter-face font is used for text indatabase fields. Change yourinterface font if you need
characters that are not in the current interface font(Tools/System/Fonts).
The Character Map window can remain open forinsertion of additional special characters in the sametext layer or database table. Simply continue enter-
ing text and use the Character Map window toinsert glyphs as needed. For direct keyboardentry of unusual glyphs, press F2 followed bythe input entry code shown in the third columnof the Character Map window and press F2again.

Other Legend TypesMap grids and text are saved as a part of the layoutobject so when you do a Save As and create a newlayout object, the original is not affected by changesto text and map grids in the new layout. Legends,except for multi-object legends, cannot be alteredin one layout and maintained in their original formin another because changes are saved to the legendobject rather than as part of the layout object.
The legends not yet discussed in this booklet arecolor sample, color scale ranges (available only inView window legends and as part of a multi-object
Color SampleLegend Display Controls
Feature Map with defaultColor Sample legend
legend), and separate point and polygon legends.The controls for all of these legend types are nearlythe same as those already described. Colorsample legends are intended for raster ob-jects that contain categorical data,such as Feature Mapping results.You get a legend entry for eachactive entry in the color map, which isidentified by default by its cell value. Thenumber of cells that have this value is also providedin parentheses on the same line as the color sampleand cell value. You can of course edit these entries Point Legendto replace the cell value with the class nameor to convert the number of cells to groundarea. Color scale range legends are a crossbetween continuous color scale and colorsample legends. You specify the number ofsamples you want and discrete samples areprovided to represent a range of values. De-sign elements for raster legends as part of amulti-object legend are found on the Legendpanel of the Raster Layer Controls.
Like line legends, point and polygon legendsuse a style object to derive the samples andtheir labels. You can edit the default labels soyou can include spaces and punctuation ifdesired.

CAD Snapshots of Database TablesTabular database information can be included inlayouts in the form of CAD snapshots. You can makethese snapshots in the Database Editor, while dis-playing the associated object alone, or while build-ing the layout. This snapshot can include all of atable’s fields or selected fields can be hidden and notincluded. A CAD snapshot is not georeferenced, so
it needs to be placed in a separategroup with an adjustedrelative scale. Groupswith appropriate rela-tive scale have alreadybeen created for you inthis exercise.
The headings that ap-pear over the CAD snapshots once added to yourlayout are not visible in the initial layout becausethey are attached to empty groups, namely the groupsthat you add the snapshots to.

Virtual (computed and string expression) fields area powerful tool for many different applications. Inthis exercise, you are given a vector object that hasa database table with an implied one-to-one attach-ment type and a single, computed field. Without anydata entry, except the expression for the virtual field,you get a unique record associated with each elementthat supplies the information specified in the expres-sion. You should look at the expression for thisvirtual field.
The expression combines the values from three fieldsin other tables with the formatting codes needed toget right aligned numbers that correspond to thenumbers on the symbols and left aligned schoolnames. You do not normally include formattingcodes in a virtual field because they do not affect thedatabase display. However, the intent was for thistable to provide a legend so the formatting may aswell be generated by the expression rather thaninserted one line at a time later. Note that the numbersare not part of the sym-bols—they are on-the-fly labels generated byattribute.
This exercise cannot becompleted in TNTmipsFree or Basic.

Hinting and Antialiasing Geometric LinesAliasing is the stairstep effect in lines drawn digi-tally using a fixed, uniform color and intensity.Antialiasing removes or reduces the jagged effect.TNTmips accomplishes antialiasing using transpar-ency to provide a smoother appearance for lines.Antialiasing is applied to any line that has a widthof less than 1.5 pixels at the scale being drawn. Theillustrations below were captured either from theView window or from a magnifier utility.
Hinting uses transparency to represent lines thatwould be less than one pixel at the current scale.Unlike antialiasing, which uses transparency tosmooth the line where it would appear jagged, hint-ing applies to the line as a whole. The degree oftransparency is proportional to how much less thanone pixel the line width would be at the scale drawn.Hinting and antialiasing can be turned on and offindependently for each View or for all newly openedViews.
Hinting and antialiasing can be applied to all geo-metric object types. In this exercise they are appliedto a TIN object being drawn as elevation contours.

Using Map Layouts in PresentationsWhen preparing a layout for printing and for use ina presentation by projector (either directly in TNT-mips or from a presentation software package, suchas PowerPoint), new considerations come into play.White is generally not used as a presentation back-ground color, but it is the background color for PageLayout. You do not want a black background either,or the text will “disappear.” The methods used in thisexercise presume that screen capture provides highenough resolution for your presentation purposes. Ifnot, there are a number of other strategies* to makepresentation materials but the TNTmips Free sizelimits are applied to your exports.
The small text groups are deleted from the layout toillustrate you need not keep all groups of the originalmap for the screen capture. There is relatively littlework to change this layout from hardcopy to displaywith appropriate attachments because, starting onpage 12, specific attachments are made to Group 1rather than the default Page attachment. You choosethe Select tool in the next to last step so the placementrectangles are not visible for screen capture.
STEPS
click on the Openicon, and select the St.Marys layout (p. 25)
click on the LayoutPlacement icon onthe View window toolbarthen on the name of thelegend group to select it
change the HorizontalAttachment to the kmgroup Center to Centerand the Vertical Attach-ment to the km groupTop to Bottom with aspacing of about 0.2"

Printing to Files and Network PrintersTNTmips provides many different methods to printlayouts. You can print immediately creating only atemporary raster, you can print to a raster object (4-bit dithered or 24-bit without dithering), or you canprint to a print-file (no printfiles or 24-bit unditheredin TNTmips Free). You need not have the layoutopen in a display process to print; printing fromlayouts, print rasters, and printfiles is available usingthe Main / Print From menu options, which use thesaved objects or files without opening a View win-dow. Print-rasters and print-files are more conve-nient than layouts when printing from a machineother than the one on which the layout was createdbecause once you have a print-raster or print-file, theinput objects are no longer necessary. (Almostinvariably, some component of the layout is over-looked or placed in a file with a different name whenthe layout is copied.)
Print-raster objects can be viewed like any otherraster object in TNTmips (but not in TNTmips Free,the print raster for an 8.5 x 11" page at 300 dots perinch is 2550 x 3300 cells). A print-file is notviewable; it contains the information required bythe printer to print the page. A print-file is actually
a pair of files, both with the name you assigned butone has a .p1 extension (large file) and the other hasa .prf extension (small file). When printing fromTNTmips Pro, but not from TNTmips Free, you canprint over multiple pages, which gives you .p1, .p2,and so on, where the number corresponds to the pagenumber. There is still just one .prf file. Printfiles canbe printed on machines without TNTmips installedby copying them to the printer port (see p. 8 of thePrinting booklet for explicit instructions).
You can also print to any network printer availablewhen you print from TNTmips. If running Windowsor on a Mac, you have the option of letting Windows/Mac OS X or TNTmips do the dithering. You shouldtry both to see if you have a preference.
STEPS if you have access to
Windows printers, clickon the Open icon,and select anyhardcopy layout de-signed for A (8.5" x 11")or A4 sized paper
choose Display/Print inthe Display Manager
click on the Use Win-dows Printer button
click on the Ditheringtab, and check that “LetTNT do the dithering” isselected
click [Print], and collectyour print once the Printprocess is finished
choose Layout / Print,click on the Dithering taband choose “Let the Win-dows printer driver do thedithering and colormatching”
click on [Run], collectyour print when done,and compare
Note: the temporary rasterfor printing with theWindows driver requires sixtimes the drive spaceneeded by TNT (24-bitversus 4-bit).

3D and Transparency in LayoutsYou can make use of both 2D and 3D groups whendesigning layouts for display or hardcopy. Anelastic box is provided with the 3D Viewpoint Selec-tion window that opens when the Viewpoint Con-trols are opened so you can select the area of the 3Dview to include in the layout. You also have all the3D Viewpoint controls that you use when workingwith a separate 3D group.
Transparency can be used with any layer type. Oncetransparency is set for viewing, there are no addi-tional settings to get the transparency effects toprint. Transparency is set for vector, CAD, and TINlayers as part of the polygon drawing style. Trans-parency can be set for rasters in a variety of ways.You can assign a percentage transparency to indi-vidual color map values; you can assign a percent-age transparency to the raster as a whole (Optionspanel of the Raster Layer Controls); or you canselect an 8-bit mask that provides transparencyvalues for the raster displayed (0 is fully transparent,255 is opaque).

click on Redraw
3D groups in layouts have an associated 3D View-point Selection window in addition to the View-point Controls. This window lets you choose whichpart of the 3D rendering you want to include in thelayout and also has an Apply Changes button toindicate you are ready to update the changes madein viewpoint and/or area selected to the 3D group inthe layout.
You can add a new 3D group to a layout and set upthe viewpoint and selected area, or you can add apreviously saved 3D group to a layout. You can alsosave a 3D group that you have set up in a layout andthe selected area, as well as the viewpoint, will beretained, as it is for the 3D group you add in thisexercise.
You can resize and reposition the existing box ordraw a new box in the 3D Viewpoint Selectionwindow. The box functions like any other elasticbox in theTNT prod-ucts.
The combination of3D and transparencyin the group added,give the butte a morerugged appearancewhile blending wellwith the 2D image.

click on the AddMap Grid icon
set the same map gridsettings as on p. 6
experiment with the dif-ferent options on the 3Dtabbed panel
on the Labels panel,check that the Show in3D options are checked
You can have map grids in 3D as well as 2D groups.There are additional controls for 3D map grids. Theseinclude which vertical axes to show, where to posi-tion the neatline, and whether to include vertical tickmarks. Map grids, like scale bars and text, are storedas part of the layout not as a separate object.
All of the settings that are unique for 3D groupsappear an the 3D tabbed panel of the Map Grid LayerControls, which is present only if you are adding amap grid to a 3D group. Your options for vertical axesare None, Farthest, Farthest Two, Farthest Three, andAll. The values displayed on the vertical axes reflectthe cell values and are not scaled. Here the cell valuesare 1 to 255. The labels at 100 meter intervals wouldbe 1 to 301. You can change either end of the Z Rangeon the Extents panel of the Map Grid Layer Controlsif the Lock to group extents toggle is not on. Thereare settings that pertain to Z values on all panels ofthis window except the Graphics panel.
The default 3D neatline outlines the edge of thesurface. To get a good fit between the drape layer andthe neatline you need to decrease the error toleranceof the surface layer, which means the group will takelonger to render. You can vary this setting to see itseffects.
This rendering ofa 3D group with mapgrid shows all fourvertical axes and the ShowNeatline Below toggle on.
Additional 3D options are set on the 3D tab of theRaster Layer Controls for the drape layer.

Making Map Layouts
Attach Groups by GeoreferenceGeographic attachment of groups uses georeferenceinformation to provide exact geographic overlay ofthe layers in separate groups. Using georeferenceinformation as a means of establishing group posi-tion lets you organize the components of your lay-out. You can organize layouts with many layers intological groups, such as parcel maps, wetlands, his-toric sites, and watersheds.
This type of organization makes it easy to locateparticular layers if you have tens or hundreds in alayout. It also makes it easier for users that are notvery familiar with your geodata, such as clientsviewing your data in TNTatlas, to selectively turnlayers on/off for viewing a whole group at a time orto locate individual layers within these groups.
Separate groups and layers can be turned on/offindividually for viewing and/or printing. A right-click on the Show/Hide box reveals a menu with asmany show/hide options as appropriate for yourcurrent display. Thus, you can use the same layoutto print maps that present different themes deter-mined by your current needs.

Map Scale-Controlled VisibilityMap scale-controlled visibility lets you set whichgroups, layers, and/or geometric elements are visibleat any map scale. When geometric features are denseat full view, there is no point in displaying them untilyou reach a map scale at which they are well resolved.Your raster imagery may not be of sufficient resolu-tion for display at the larger map scales where geo-metric display is appropriate (i.e., one raster cell mayoccupy many screen pixels). Remember that mapscale is expressed as a ratio such that a map scale of1:200 is a larger map scale than 1:100,000. The firsttime a geometric object is displayed, TNT’s displayprocess will warn you and suggest an initial mapscale if the elements are too dense for reasonabledisplay at full view.
The map scale ranges set for viewing are also used forprinting. The group/layer/element must be visible atthe layout scale set for printing for it to be printed.Thus, you could print maps with different layersshown from the same layout by changing only thelayout scale and perhaps repositioning the layout onthe page.
For more information on map scale-controlled vis-ibility, see the Working with Massive Geo-data Objects tutorial booklet and the Layersin View Controlled by Scale and Elements inView Controlled by Scale Quick Guides.
STEPS
open the layout in theMapScale Project File
zoom in and out andwatch layers come andgo
right-click on the layoutname and choose SetScale Ranges
notice which layers havemap scale-controlledvisibility
map scale 1:10,000,000 map scale 1:200,000
The need for map scale-controlled visibility is difficultto demonstrate in TNTmipsFree-sized data sets. Thelayers in the layout usedhere were extracted fromdata sets with globalextents. The vector-containing groups aregeographically attached tothe image group.
Keep this layout open forthe next exercise.

Rendering Displays to Various FormatsIn addition to hardcopy output, you can render agroup or layout to a raster object in a variety offormats, a KML (or KMZ) file, an SVG file, or a PDFfile. The raster formats supported are RVC, JP2,GeoJP2, GeoTIFF, TIFF, JPEG, and PNG. All of theseoutput types are georeferenced either internally orwith an accompanying world file.
Render to Raster creates a single 16- or 24-bit com-posite color raster from all of the layers in your groupor layout. You can set the raster size by number ofrows and columns or by entering the cell size.
You get layer controls with KML, SVG, and PDF fileseither automatically or optionally. The additionalcontrols provided depend on the output formatselected. When rendering to KML, you have theoption to open the result in Google Earth. With PDFfiles you can choose to open the result in your defaultAcrobat product.
STEPS
with the layout open fromthe previous exerciseopen, choose Display/Render to/KML
on the Options tabbedpanel, set the Extents toEntire Display and turnon the Show result inGoogle Earth and Com-press to KMZ toggles
on the Raster Controlstab, set the cell size to500 meters
click on the GeometricControls tab and set theCoordinate Accuracy to100 meters

In Summary and DetailThink carefully before deleting groups in a layout.Have you established any attachments? Are yougoing to want some other layer in that position? If so,delete the unwanted layer(s), not the group.
If a layout is destined for reuse, pay attention to therelative scale settings. If you plan to print the samelayout on a variety of paper sizes, set the scale for textand legends relative to a specified map scale for bestresults. If you want to use the same layout butreplace the main image with another at a differentmap scale, set the scale relative to the design scale.
Attach groups to the page if you want them to becentered. Attach groups to the margins if you wantthem to remain in a fixed position on or near one ofthe margins. Attach groups to other groups if youwant them to move together.
Non-printer DestinationsIn addition to directly printing your hardcopy lay-outs, there are a number of other choices for printers.One is to print to a TNTmips or Windows printfile,which can be printed from a computer not runningTNTmips (see the Printing tutorial booklet for moreinformation). You can also convert your layouts toa number of familiar file formats, such as TIFF, EPS(for Adobe Illustrator), PDF, and SVG. You get morecontrols using the render-to options discussed in theprevious exercise for the supported formats (all butEPS), which is the recommended approach. Youcannot print to these file types from TNTmips Free.
Sketch layers are added to the active group andderive their georeference from that group. Asketch that extends beyond the other layers in agroup changes the group extents. All of thesketched lines in the partial layout shown at rightare in the same group as the large database table.The table didn’t move when the sketch was drawnbecause it is attached to the left and bottommargins.
The partial layout aboveconsists of a variety ofscreen captures tiedtogether with a sketch layerand annotation text.
