networkx.readwrite.read_shp¶

networkx.readwrite.read_shp(path, simplify=True, geom_attrs=True)[source]¶

Generates a networkx.DiGraph from shapefiles. Point geometries are translated into nodes, lines into edges. Coordinate tuples are used as keys. Attributes are preserved, line geometries are simplified into start and end coordinates. Accepts a single shapefile or directory of many shapefiles.

“The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software [R1285].”

Parameters:

path : file or string File, directory, or filename to read. simplify: bool If True, simplify line geometries to start and end coordinates. If False, and line feature geometry has multiple segments, the non-geometric attributes for that feature will be repeated for each edge comprising that feature. geom_attrs: bool If True, include the Wkb, Wkt and Json geometry attributes with each edge. NOTE: if these attributes are available, write_shp will use them to write the geometry. If nodes store the underlying coordinates for the edge geometry as well (as they do when they are read via this method) and they change, your geomety will be out of sync.

Returns:

G : NetworkX graph
