Trail Rail

Simple app to follow GPX track

Written by: Pavel Machek

After GPS fix is acquired, it displays familiar arrow with road in front of you. It never stores whole track in memory, so it should work with fairly large files.

On startup, you select track you want to work with. After it is loaded, few screens are available.

  1. "Follow" -- displays arrow on the track. Should work well as you follow the route. If you get lost, press top right corner to "recover".

  2. "Map" -- can draw a track around your current position. Press top right corner to redraw.

  3. "Statistics"

Press touchscreen corners to select functions

Preparing data

GPX files can be obtained from various services, www.mapy.cz is one of them (actually uses openstreetmap data for most of the world).

"gpx2egt.sh < file.gpx > t.name.egt" can be used to prepare data, then upload it to watch. Filename has to be in t..egt or r..egt format (suggestion is to use t.* for track "there" and r.* for return track).
