Topology - Family of Functions

The pgRouting’s topology of a network represented with a graph in form of two tables: and edge table and a vertex table.

Attributes associated to the tables help to indicate if the graph is directed or undirected, if an edge is one way on a directed graph, and depending on the final application needs, suitable topology(s) need to be created.

pgRouting suplies some functions to create a routing topology and to analyze the topology.

Additional functions to create a graph:

Additional functions to analyze a graph:

The following functions modify the database directly therefore the user must have special permissions given by the administrators to use them.



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.

These proposed functions do not modify the database.
