LEI Electronics 6 manual GPS Data File

create a fresh Custom Map File. You can delete the old one, or just save the new custom map over the old one.

GPS Data File

This file format contains all the GPS navigation information (waypoints, event marker icons, routes and trails) used by your GPS unit and MapCreate. The file extension is *.usr (for User file) and the file is saved either to your hard drive or directly to your MMC or SDC. As with other Windows-based files, you can drag and drop these files from the hard drive onto an MMC or SDC, which is then loaded into your GPS unit. You can open and make changes in a GPS Data File once it has been created. The contents can include any combination of waypoints, routes, trails and event marker icons. The information shows up graphically on the Master Map as symbols with names. The same information is also available as text in a list window, such as the Waypoint List window. Your GPS unit saves field-collected GPS information in the same format so MapCreate can be used to save valuable travel or adventure data for a later trip. This also makes it easy to exchange GPS data with friends using Lowrance or Eagle GPS equipment.

ASCII Text File

This is a universal text file format compatible with word processors and other software programs. MapCreate can exchange routes and waypoint lists with other mapping programs by importing and exporting GPS information as comma-delimited ASCII text files. ASCII (pronounced "ask-ee") uses the *.txt file extension. You don't need to work with these files, unless you plan to exchange routes and waypoints between MapCreate and other mapping programs. For more information on how to use this file type, see the online Command Reference topics "Export GPS Data" and "Import GPS Data."

GPS Data Manger (GDM) File

This is an older file format used by MapCreate 5 and MapCreate 4 to hold navigation data (waypoints and such). MapCreate 6 can open these files, making the program backward compatible with versions 5 and 4. The GDM file extension is *.low. Although MapCreate 6 is designed to load and read older GPS Data Files in the *.low format, MapCreate 6.0 also allowed users to choose to save new files in the older format (though the program could not actually save them). This has been corrected in version 6.2. You can still open files in either format, but you can now only save GPS Data Files in the newer *.usr format. Please note that your MapCreate 6-compatible GPS unit can only read *.usr files.
