However, processing by GPSBabel will strip out the descriptions you might have added to the tracks. Since I can add useful information to a track, it makes sense to process kml to kml, for instance to combine several files, or just to add lengths. Since I’m a metric kind of guy, you'll get the length in kilometres.Ī second feature has to do with processing kml to kml. All I had to do was translate from JavaScript into Python. It actually became trivial after I found some code by Chris Veness to do the calculation. Since my tool is rewriting the output kml file from GPSBabel anyway, it was not very hard to calculate the total length of the tracks and add that information to the description of the track. There are some web tools available to claculate this length, but it should be classified as a missing feature. Google Earth has no method of calculating the length of a track, at least not easily. Macintosh users may find the droplets that are listed below useful to perform these tasks without having to use the command-line. Transfer a track to my Garmin GPS device. Take a file from Google Earth, and create a gpx file with multiple tracks, but with each track containing no more than n points, with n=500 for my device. In this mode, the script will produce a single file with multiple tracks in it. Take one or more tracks from the dutch “Fietsrouteplanner” (bicycle route builder) in gpx format, and turn it into a Google Earth file. This mode will reate a single track, that is: separate parts of the file will be glued together, to compensate for loss of reception or the tea-break. I prefer to transfer this file, rather than read the track-log from the device. Note that my GPS device already creates a track log in gpx format, straight on the µ-SD card. Take a track from my Garmin handheld GPS device, and translate it into something Google Earth will read. When developing “Whereabouts”, I hade the following use scenarios in mind: After playing with the options for a while, I found a set of option that produced something pretty close to what I wanted, and I took it from there. Besides, I like the output of GPS Visualizer, and GPSBabel just adds too much information. Gpsbabel gpx to kml how to#Practically all conversions of GPS-related data can be done with GPSBabel, but it has too much options, and I grew tired of figuring out how to achieve what I wanted it to do. The “Whereabouts” Python script is a helper tool to handle geolocated data more easily. Gpsbabel gpx to kml software#This software is licenced under the CC-GNU GPL.
