Repeat for all maps needing geo-registering.

N.B. White spaces round the edges where maps overlap will be automatically

resolved in Mapserver.

If user puts geo-registered maps back into Photoshop, the map resolution will have

been altered, this does not matter.

If any files need extra cropping work doing to them, after geo-registering then

PC Start menu: PROGRAMS > ACCESSORIES > WORDPAD

Open world file [file name].tfw

Remove all line spaces that ARCGIS has added

SAVE (as same file)

Open GEOTIFF-EXAMINE

Select filename

All data will appear in the world file column on the right.

Click the button to transfer the data to the GeoTiff fileClick UPDATE REFERENCING IN TIFF FILE button

Will confirm the file is now geo-registered.

Click close

Tiff file is again ready to be used in ARCMAP.

Ensure all new files are in same directory as any old files to use all together when

creating one new coverage.

N.B. All [file name].rrd files and all [file name].aux files can be deleted as created by

ARCGIS and not needed.

Create Shapefile

PC Start Menu: RUN

Then type

cmd

G:

cd maps\tileindices

gdaltindex [name of tileindices to be created].shp ../directory structure to file/*.tif

[e.g. gdaltindex lus_stamp.shp ../r_data/lus_stamp/*.tif]

exit

This will create new tileindices in the right directory with the right pathways to the

data so will work on pc and on server.
