ADM to GPX
Convert a Garmin ADM database file to a GPX file
User data exported from later model Garmin GPSmap marine GPS sets consists of ADM files written to a VFAT-formatted SD card.
This data includes user-generated waypoints and routes, and recorded GPS tracks.
adm2gpx converts this data to industry-standard GPX records that may be imported into third-party mapping and GPS software.
