Topology - Family of Functions¶
The pgRouting’s topology of a network, represented with an edge table with source and target attributes and a vertices table associated with it. Depending on the algorithm, you can create a topology or just reconstruct the vertices table, You can analyze the topology, We also provide a function to node an unoded network.
- pgr_createTopology - to create a topology based on the geometry.
- pgr_createVerticesTable - to reconstruct the vertices table based on the source and target information.
- pgr_analyzeGraph - to analyze the edges and vertices of the edge table.
- pgr_analyzeOneWay - to analyze directionality of the edges.
- pgr_nodeNetwork -to create nodes to a not noded edge table.
Proposed
Warning
Proposed functions for next mayor release.
- They are not officially in the current release.
- They will likely officially be part of the next mayor release:
- The functions make use of ANY-INTEGER and ANY-NUMERICAL
- Name might not change. (But still can)
- Signature might not change. (But still can)
- Functionality might not change. (But still can)
- pgTap tests have being done. But might need more.
- Documentation might need refinement.
- pgr_extractVertices – Proposed - Extracts vertices information based on the source and target.
