cost_distance
(friction_layer, geometries, max_distance)¶ Performs cost distance of a TileLayer.
Parameters: - friction_layer (
TiledRasterLayer
) –TiledRasterLayer
of a friction surface to traverse. - geometries (list) –
A list of shapely geometries to be used as a starting point.
Note
All geometries must be in the same CRS as the TileLayer.
- max_distance (int or float) – The maximum cost that a path may reach before the operation.
