Thanks to a big help of my wife I’ve finally published separate pages for all 15 stages of the GR 20 trail. Every page contains a short description (rather too short for the time being) of the particular stage and a map. The maps use Google mapping engine as does the map of the whole trail, but they are more detailed — they include all alternate routes and even the basic route consists of much more points.
These new, high-resolution routes are actually the first result of my work on accurate trail recording and mapping. I already have tracklogs of GR 20 and some other Corsican long-distance paths that I’m going to publish as GPX files for GPS devices very soon.
