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.
GpsPhoto.pl geotags digital photos by using GPS track data recorded at the same time. Matches are based on closest timestamps. An optionally generated Google Earth KML or KMZ file contains the GPS tracks and the geotagged photos.
