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.
