Add Scanned Map Command

Before you can use your map image in ExpertGPS, it must be added to the Map Library and calibrated.

Adding a New Scanned Map (World File)

To add a new map to the Scanned Map Library, do the following:

The Open Scanned Map dialog will appear. Select World File (*.jgw;**.tfw;*.pgw;*.bpw) in the Files of Type list.
Open Scanned Map dialog menu

The map will be added to the Scanned Map Library. The map has been calibrated using the calibration points from the Map Calibration File. The projection and datum are set to default values (Equirectangular and WGS84) and must be changed.

Select the newly-added scanned map, and click Edit to specify the projection information located in the collar of your map in the Edit Scanned Map dialog.
