Hi, I am new to Mapnik and was thinking about using Mapnik as the mapping solution for a desktop GIS application. My initial thoughts were to use:
- Python - wxPython - Mapnik With other packages (OGR/GDAL, Shapely, pyproj, etc.) if needed. I have looked at the Mapnik samples and API and I know it can make a great looking map, what I am not sure about is the ability to add a temporary/dynamic layer. What I would like to be able to do is have Mapnik set up with static background mapping data and add markup (or temp layers) to Mapnik made up of geometry (points/lines/polys) calculated elsewhere. Is this possible in Mapnik? I see there are some provisions for a "Memory Datasource" but it looks like it only supports points? Anyone have any thoughts on how this might be done? I thought about having a text based OGR layer (GeoJSON?) added to Mapnik and changing this file on disk; doesn't really seem like a good idea though... Any info or thoughts are appreciated.
