Color contrasts

• Red roads vs brown contours hard to distinguish – use gray contours

• All colors lighter than black labels – few halos• This is not a road map – do not use whole contrast

range on road categories• Leave contrast available for update

and overlay of operational information– magenta could be used for additions if no magenta symbols

• Contrasting outlines on point symbols separate from each other and background

Multiscale durability:good point overlaps

Halos and casings

- Dull greenish brown halo on contour labels

- Slightly blue halo on hydro labels

- Slightly beige casing on local roads

- Slightly gray fill in road shields

- Slightly gray drop shadow on populated place names

Other labels dark enough to read over content

Geoprocessing for map design

• Contour cracking for faster drawing• Polygon-to-line for dashed lines• Dissolve on attribute to join small segments (e.g., roads)• Pair layers with version not symbolized for labels with

different classes (e.g., flowlines, admin areas, populated places)

• Flowline upstream drainage area (UDA) calculated for stream tapering

• Smooth DEM first to create generalized contours and hillshade for terrain
