get_network_ratio
(df, edges, initial_buffer=500)[source]¶ Link polygons to network edges based on the proportion of overlap (if a cell intersects more than one edge)
Useful if you need to link enclosed tessellation to street network. Ratios can be used as weights when linking network-based values to cells. For a purely distance-based link use
momepy.get_network_id()
.Links are based on the integer position of edge (
iloc
).- Parameters
- dfGeoDataFrame
GeoDataFrame containing objects to snap (typically enclosed tessellation)
- edgesGeoDataFrame
GeoDataFrame containing street network
- initial_bufferfloat
Initial buffer used to link non-intersecting cells.
- Returns
- DataFrame
