Description
This dialog box allows you to convert the latitude and longitude data from your GPS into a coordinate system of your choice. For example, you may wish to match the coordinate system used in your survey maps. You can display location data as Easting and Northing coordinates measured from a horizontal datum. You can also set the zone so that accurate location data is embedded in any GeoTiff files that you create.
