Geospatial Tools for Visibility Analysis
Create a polygon representing an occluder
Calculate isovist from one or multiple viewpoints
Construct isovist from (partially occluded) rays
Get rays from the viewpoints within a maximum isovist
Get viewpoints from an arbitrary geometry
Merge the viewpoint isovists
Determine the non-occluded segments of the rays
Provides tools for visibility analysis in geospatial data. It offers functionality to perform isovist calculations, using arbitrary geometries as both viewpoints and occluders.
