See INSTALL file for installation instructions Mapnik is an OpenSource C++/Python toolkit for developing GIS (Geographic Information Systems) applications. At the core is a C++ shared library providing algorithms/patterns for spatial data access and visualization. Essentially a collection of geographic objects (map, layer, datasource, feature, geometry), the library doesn't rely on "windowing systems" and can be deployed in any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development. High-level Python bindings (boost.python) facilitate rapid application development, targeting zope3, django etc. Mapnik is a free software and is released under LGPL (GNU Lesser General Public Licence) (see COPYING)
