I have a Garmin 78s marine GPS receiver and it stores tracks in GPX
format. This is an XML encoded set of points giving longitude, latitude, time and sea depth. Garmin support viewing this via their Garmin Express product, but there only seem to be Windows and Mac versions. I’ve emailed them and await a reply. In the mean time, does anyone know of any Linux products that will emable me to view track data on a decent sized screen? I don’t want to re-invent the wheel by coding up a hack myself.
