Mapnik
Mapnik is an open source toolkit for rendering maps. Among other things, it is used to render the four main Slippy Map layers on the OpenStreetMap website. It supports a variety of geospatial data formats and provides flexible styling options for designing many different kinds of maps. Mapnik is written in C++ and includes high-level Python bindings. It uses the AGG library and offers anti-aliasing rendering with subpixel accuracy. It can read ESRI shapefiles, PostGIS , TIFF rasters, .osm files, and any GDAL or OGR supported formats.
