4SIM

This is a demonstration of the a 4 Sides Intersection Model (4SIM) Python package. It demonstrates how 4SIM can be used to calculate betweeness of spatial objects. 29_unimelb_buildings.shp holds geometries of 29 buildings and unimelb_buildings_triplets.csv defines triplets of buildings (their ids) that should be considered in the betweeness analysis. The unimelb buildings are sourced from the OpenStreetMap.
