edges_from_line(geom, attrs, simplify=True, geom_attrs=True)

Parameters

geom: ogr line geometry :

To be converted into an edge or edges

attrs: dict :

Attributes to be associated with all geoms

simplify: bool :

If True, simplify the line as in read_shp

geom_attrs: bool :

If True, add geom attributes to edge as in read_shp

Returns

edges: generator of edges

each edge is a tuple of form (node1_coord, node2_coord, attribute_dict) suitable for expanding into a networkx Graph add_edge call

.. deprecated:: 2.6

Generate edges for each line in geom Written as a helper for read_shp

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
