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.
