Centerline
Roads, rivers and similar linear structures are often represented by long and complex polygons. Since one of the most important attributes of a linear structure is its length, extracting that attribute from a polygon can prove to be more or less difficult.
This library tries to solve this problem by creating the the polygon’s centerline using the Voronoi diagram. For more info on how to use this package, see the official documentation.
Features
A command-line script for creating centerlines from a vector source file and saving them into a destination vector file: create_centerlines
$ create_centerlines input.shp output.geojsonThe Centerline class that allows integration into your own workflow.
>>> from shapely.geometry import Polygon
>>> from centerline.geometry import Centerline
>>> polygon = Polygon([[0, 0], [0, 4], [4, 4], [4, 0]])
>>> attributes = {"id": 1, "name": "polygon", "valid": True}
>>> centerline = Centerline(polygon, **attributes)
>>> centerline.id == 1
True
>>> centerline.name
'polygon'
>>> centerline.geometry.geoms
