I have a shapefile with areas (eg. a simple world map with countries - polygons, epsg:4326). I also have a point (lat, lon coordinates).
What's the simplest/easiest way to figure out in which polygon (country) that point is? Polygons are not overlapping.
I have to do this server-side for many points, so i'm thinking about using mapnik, or any other library for that. (Linux server, opensource/free software only).
