I'm setting out to follow various pilgrimage routes from Erfurt Germany, to Rome (roughly in the steps of Martin Luther, for those who care). I've assembled various snippets of routes toward Santiago de Compostella, my own route through the Alps, and the Via Francigena from Pavia southward. These are all available as downloadable GPS tracks; I have merged the tracks (using Garmin BaseCamp) into one, long track, over 27k waypoints over 1732km!
Now I need to plan stages, and am puzzled as to how to go about it. I've been using Google Earth to work on the tracks, but you can't merge them in it. I want to be able to break up the long track into day-long segments of roughly 30km, but this is proving difficult with the software I'm able to find (Mac 10.4, unfortunately). I otherwise wouldn't bother, but this is a sponsored trip and I need to arrange for lodging each night, know what monasteries, castles, I'll be passing by, and generally let everybody know where I'm going to be.
After converting the merged GPX file from Garmin BaseCamp into KML (using GPSBabel), it's too big to work with in Google Earth, and besides, you can't measure track length in Google Earth!
I seems to me that this should be a paltry task for the right software. Can anybody help me out with it?
