Users of global satellite positioning devices, used to collect location data, need a way to exchange such data between a device and software programs such as Street Atlas USA, Topo North America and XMap, all of which put tracks and routes on a digital map. Store the maps with the GPS data as image files, and transfer them to any image editing program such as Adobe Illustrator for use in graphics applications.
