This repository contains a fork of github.com/mapnik/mapnik, used mostly for rendering maps on mapy.cz. Main differences against upstream are:
- Placement
line-max-angle - Text placement method
combined - Text placement method
angle - Unification of placement options
- CollisionSymbolizer
- Keyed collision caches
- Anchors
- Pattern symbolizers improvements
- Shadows with building symbolizer
- XSLT preprocessing
Recently merged:
- Placement

Mapnik is an open source toolkit for developing mapping applications. At the core is a C++ shared library providing algorithms and patterns for spatial data access and visualization.
Mapnik is basically a collection of geographic objects like maps, layers, datasources, features, and geometries. The library doesn't rely on any OS specific "windowing systems" and it can be deployed to 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.
For further information see http://mapnik.org and also our wiki documentation.
See INSTALL.md for installation instructions and the Install page on the wiki for guides.
