Note: This page describes an obsolete version of GPSBabel that may substantially differ from the current or development version.

Geogrid-Viewer ascii overlay file (.ovl) (ggv_ovl)

This format can...

  • read and write waypoints

  • read and write tracks

  • read and write routes

Overlay files used by Geogrid™-Viewer has to be in ASCII format. Make sure you save the files correctly.

Lines or polygons within the Geogrid™-Viewer (type 3 and 4) will be converted to tracks, except they are grouped. In this case GPSBabel creates routes.

During the creation of an overlay file, a circle will be added to each position of a waypoint or a route.
