Maybe later I will post something on using Viking, but that’s besides the scope of this post. Stuff like that is easily corrected with Viking, a nice GPS/track/waypoint editor, that runs on Linux (POSIX) and Windows, and is available under the GPL v2 license. I don’t know about you, but in my case, a track always contains some stuff that I don’t want to show up in the end result: mistakes that I made during my ride, like entering dead-end streets, or those extra meters that you make, looking for a place to park for a coffee break. Now, I would like to create a route out of this track, that I can share with others. For example, a drive of about 60 km that I took a few weeks back, gave me a track consisting of over 2600 trackpoints. Typically, such a track contains many trackpoints. Suppose you have a GPX file, containing a track. This post is about something else, namely how to convert a GPS track (that you created by driving, downloaded somewhere, etc.) into a route, with the same criteria as last time. The main problem that I was trying to solve, is how to create a “real” route that my Zümo will understand, built out of a minimal amount of route waypoints (that show up as such on the Zümo when navigating), rather than possibly thousands of trackpoints, that are hard to process for the device and don’t give you as much navigation flexibility. Last week, I blogged about creating routes for a Garmin Zümo, using Google Maps and GPSBabel. Categories: GPS and mapping, Motor, Nerd Stuff
