Urbanistic Polygons

Builds areas based on urban properties and merges similar areas of OSM for analysis reasons.

The algorithm works in three steps:

1. Build a planar graph based on all types of barriers that are relevant, for example:
   • Roads.
   • Water bodies.
   • Landuse polygons.
2. This planer graph defines polygons by definition. Assign urban scores to each polygons. We use the following categories but they are configurable:
   • water
   • residential
   • rural
   • industrial
3. Merge polygons based on their similarities and the type of barrier between them.
