Convenience Functions¶
The following functions are general purpose convenience functions that might be useful when building a larger application or handling input from say an Ajax handler.
- pgr_pointToEdgeNode - convert a point geometry to a
vertex_idbased on closest edge.- pgr_flipEdges - flip the edges in an array of geometries so the connect end to end.
- pgr_textToPoints - convert a string of
x,y;x,y;...locations into point geometries.- pgr_pointsToVids - convert an array of point geometries into vertex ids.
Distance Matrix Functions¶
These function my be helpful when you need to create or manipulate distance matricies, like for TSP or VRP related problems.
- pgr_pointsToDMatrix - Create a distance matrix from an array of points.
- pgr_vidsToDMatrix - Create a distance matrix from an array of
vertix_id.- pgr_vidsToDMatrix - Create a distance matrix from an array of
vertix_id.
