I am new in PostGIS, and I am trying to create connectivity(using topology) between 3 sets of points and polyline to model an electrical distribution network.

Does anyone know how to do this?

  • If you're data is already topologically correct and connected, you could possibly use the PGRouting tools to build the connectivity and the routing functions could give you what you need ... maybe @dkastl would have some thoughts... – DPSSpatial Apr 14 '18 at 15:05

The question you're asking is not very specific, and as such, you're probably best off getting started, and coming back to ask questions when you find specific issues.

I recommend you read these as a starting point:

  1. The documentation on PostGIS Topology
  2. A tutorial on PostGIS Topology.

I haven't run through these, and there doesn't seem to be much material online, but that might actually be an indication of how easy it is to do!

Good luck.
