Release Notes

  • A C and C++ library for developer was created

    • encapsulates postgreSQL related functions
    • encapsulates Boost.Graph graphs
      • Directed Boost.Graph
      • Undirected Boost.graph.
    • allow any-integer in the id’s
    • allow any-numerical on the cost/reverse_cost columns
  • Three Functions where completly re-factored using the developers library and functionality was added.

    • pgr_dijkstra
    • pgr_ksp
    • pgr_drivingDistance
  • Improved - Alphashape function now can generate better (multi)polygon with holes and alpha parameter.

  • Instead of generating many libraries: - All functions are encapsulated in one library - The library has a the prefix 2-1-0

  • Added proposed functions to be evaluated:

    • Proposed functions from Steve Woodbridge, (Classified as Convinience by the author.)

      • pgr_pointToEdgeNode - convert a point geometry to a vertex_id based 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.
      • 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.
  • Added proposed functions from GSoc Projects:

    • pgr_vrppdtw
  • Removed the 1.x legacy functions

  • Some bug fixes in other functions
