48 | 49 | 50 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | gpxanim 2 | ======= 3 | 4 | `gpxanim` creates animated maps from GPX tracks. 5 | 6 | It will plot the track as a line and rotate the map so that the 7 | direction of travel is always "up". 8 | 9 | The track is interpolated to achieve smooth animation. 10 | 11 | Here is an example of its output: http://youtu.be/7-tOJGSVWkc 12 | 13 | 14 | How it works 15 | ------------ 16 | 17 | 1. There are two components of `gpxanim`: a python script which 18 | controls the process, and a javascript module which updates the 19 | animation each frame. 20 | 21 | 2. `gpxanim` uses the [OpenLayers][] javascript library to render the 22 | map tiles and GPX track. 23 | 24 | 3. [WebKitGTK][] runs a small web page containing the map widget. 25 | 26 | 4. Every frame, a screenshot is captured of the map and fed into a 27 | [GStreamer][] pipeline which creates an [Ogg Theora][] video file. 28 | 29 | [OpenLayers]: http://www.openlayers.org/ 30 | [WebKitGTK]: http://webkitgtk.org/ 31 | [GStreamer]: http://gstreamer.freedesktop.org/ 32 | [Ogg Theora]: http://www.theora.org/ 33 | 34 | How to use 35 | ---------- 36 | 37 | First, get your track in GPX format. It would be better to have 38 | correct speed and course values for the trackpoints. You can use 39 | [GPSBabel][] to calculate the values: 40 | 41 | gpsbabel -i gpx -f bikehike.gpx \ 42 | -x track,course -x track,speed \ 43 | -o gpx -F synth.gpx 44 | 45 | Then run 46 | 47 | python gpxanim.py synth.gpx 48 | 49 | and it will start animating. It's not very fast unfortunately. At the 50 | end you will have a video, called `synth.ogg` by default. 51 | 52 | To see the full list of options, run 53 | 54 | python gpxanim.py --help 55 | 56 | [GPSBabel]: http://www.gpsbabel.org/ 57 | 58 | 59 | Required packages (Debian/Ubuntu) 60 | --------------------------------- 61 | 62 | apt-get install python python-gtk2 python-webkit python-gst0.10 gstreamer0.10-ffmpeg gpsbabel
