between inner and outter rings (Polygon/NultiPolygon) -- ref #2151 https://github.com/mapbox/unpacker/issues/324 ```txt A polygon consists of one or more rings. A ring is a connected sequence of four or more points that form a closed, non-self-intersecting loop. A polygon may contain multiple outer rings. The order of vertices or orientation for a ring indicates which side of the ring is the interior of the polygon. The neighborhood to the right of an observer walking along the ring in vertex order is the neighborhood inside the polygon. Vertices of rings defining holes in polygons are in a counterclockwise direction. Vertices for a single, ringed polygon are, therefore, always in clockwise order. The rings of a polygon are referred to as its parts. ``` |

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.
Installation
