Geoprocessing with Neo4j Spatial

by Andreas Wilhelm for OSGeo - Open Source Geospatial Foundation

This could include both standard spatial operations like st_buffer, st_interects, etc. (some of which are effectively supported already, but needs a more standard API), as well as topology functions for increasing connectivity. For example, there was
