PostGIS uses GEOS which is a port of JTS or CGAL depending on what "part" of PostGIS you are using. I'm unaware of CGAL's networking support, our use case depends heavily on the standard DE9-IM relationships. I would look into graph databases like Neo4j for shortest-path and other types of network analysis. They will probably perform better than pgrouting and make it easier for you to conceptualize the problem. If you need to do huge operations at scale (i.e. things that are just too big to fit in PostGIS and provide reliability/performance) or need 100% accuracy, I would go with straight CGAL. If not, higher level geometric implementations and platforms are probably going to do just fine. |
