I'm using Mapnik with OSM data and my own GPS tracks to render high-resolution PNG images of my travels. I've converted the original GPX file of a long train ride into a shapefile and added it to a layer of the map with a line symbolizer.
Unfortunately, in a number of places the track is crossed by a line that appears to be perpendicular to the track. A low resolution cropped sample of what it looks like can be found at http://elwood.jpl.se/~magnus/crossed-track.png. Is this Mapnik marking that the track has halted for a while (i.e. the train made a stop), or what's going on? The GPX file and the shapefile are both clean. I'm using Mapnik 0.7.1. Short of filtering the GPS data, can I disable this behavior? (This seems like a newbie question, but I couldn't find anything in the documentation nor in the list archives. -- Magnus Bäck [email protected] _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
