Module raw_map::geometry [−][src]
Expand description
OSM describes roads as center-lines that intersect. Turn these into road and intersection polygons roughly by
- treating the road as a PolyLine with a width, so that it has a left and right edge
- finding the places where the edges of different roads intersect
- “Trimming back” the center lines to avoid the overlap
- Producing a polygon for the intersection itsef
