Hello OpenLayers Users, I have made a little script called gpxanim creates animated maps from GPX tracks. Its purpose is for making map movies which can be used in video productions.
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 How it works 1. There are two components of gpxanim: a python script which controls the process, and a javascript module which updates the animation each frame. 2. It uses OpenLayers to render the map tiles and GPX track. The map div is rotated with CSS. 3. WebKitGTK runs a small web page containing the map widget. 4. Every frame, a screenshot is captured of the map and fed into a GStreamer pipeline which creates an Ogg Theora video file. The code's not pretty or fast but it works. There are a few options but you will most probably need to modify it to suit your needs. More details and the code are here: https://github.com/rodneythellama/gpxanim Cheers, Rodney _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
