`clean_network(G, wpath='', output_file_name='', UTM='epsg:3857', WGS='epsg:4326', junctdist=50, verbose=False)`¶

Description:

Topologically simplifies an input graph object by collapsing junctions and removing interstital nodes

Parameters:

G (networkx.graph object): a graph object containing nodes and edges. Edges should have a property called ‘Wkt’ containing geometry objects describing the roads.
wpath (str, optional): the write path - a drive directory for inputs and output
output_file_name (str, optional): This will be the output file name with ‘_processed’ appended
UTM (dict, optional): The epsg code of the projection, in metres, to apply the junctdist
WGS (dict, optional): the current crs of the graph’s geometry properties. By default, assumes WGS 84 (epsg 4326)
junctdist (int, float, optional): distance within which to collapse neighboring nodes. simplifies junctions. Set to 0.1 if not simplification desired. 50m good for national (primary / secondary) networks
verbose (boolean, optional): if True, saves down intermediate stages for dissection

Returns:
