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.
Experimental
Warning
Possible server crash
-
These functions might create a server crash
Warning
Experimental functions
-
They are not officially of the current release.
-
They likely will not be officially be part of the next release:
-
The functions might not make use of ANY-INTEGER and ANY-NUMERICAL
-
Name might change.
-
Signature might change.
-
Functionality might change.
-
pgTap tests might be missing.
-
Might need c/c++ coding.
-
May lack documentation.
-
Documentation if any might need to be rewritten.
-
Documentation examples might need to be automatically generated.
-
Might need a lot of feedback from the comunity.
-
Might depend on a proposed function of pgRouting
-
Might depend on a deprecated function of pgRouting
-
-
pgr_extractVertices - Experimental - Extracts vertices information based on the source and target.
