gpxanim creates animated maps from GPX tracks.
It will plot the track as a line and rotate the map so that the direction of travel is always "up".
The track is interpolated to achieve smooth animation.
Here is an example of its output: http://youtu.be/7-tOJGSVWkc
-
There are two components of
gpxanim: a python script which controls the process, and a javascript module which updates the animation each frame. -
gpxanimuses the OpenLayers javascript library to render the map tiles and GPX track. -
WebKitGTK runs a small web page containing the map widget.
-
Every frame, a screenshot is captured of the map and fed into a GStreamer pipeline which creates an Ogg Theora video file.
First, get your track in GPX format. It would be better to have correct speed and course values for the trackpoints. You can use GPSBabel to calculate the values:
gpsbabel -i gpx -f bikehike.gpx \
-x track,course -x track,speed \
-o gpx -F synth.gpx
Then run
python gpxanim.py synth.gpx
and it will start animating. It's not very fast unfortunately. At the
end you will have a video, called synth.ogg by default.
