General

  • [pgRouting] (http://pgrouting.org/) home page.

  • For naming:

    • < U|D >:
      • U = Undirected
      • D = Directed
    • < bbox > = xMin yMin, xMax yMax
    • M = when Export Merged button is used
  • Information about the pgr-v2.2 is also included

pgr_alphaShape

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • The alpha shape is based on the results of pgr_drivingDistance:
    • pgr-v2.0: Identifiers are converted to int4 type. costs are converted to float8
    • pgr-v2.1 & pgr-v2.2: pgr_drivingDistance for one starting vertex is used.
  • Buttons:
    • Preview: Draws in the canvas the area of the alpha shape
    • Clear Preview: Removes from the canvas objects generated with Preview
    • Export: Creates a new layer containing the multi polygon geometry named:
      (< U|D >) alphashape: <source_id> dd = <value> BBOX(< bbox >)

pgr_astar

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • pgr-v2.0, pgr-v2.1 & pgr-v2.2: Identifiers are converted to int4 type. costs are converted to float8
  • Buttons:
    • Preview: Draws in the canvas the area of the alpha shape
    • Clear Preview: Removes from the canvas objects generated with Preview
    • Export: Creates a one row per edge layer named:
      (< U|D >) astar: < source_id > to < target_id> BBOX(< bbox >)
  • Export Merged: Creates a one row with a multi string geometry layer named:
      (M< U|D >) astar: < source_id > to < target_id> BBOX(< bbox >)

pgr_bdAstar

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • pgr-v2.0, pgr-v2.1 & pgr-v2.2: Identifiers are converted to int4 type. costs are converted to float8
  • Buttons:
    • Preview: Draws in the canvas the area of the alpha shape
    • Clear Preview: Removes from the canvas objects generated with Preview
    • Export: Creates a one row per edge layer named:
      (< U|D >) bdAstar: < source_id > to < target_id> BBOX(< bbox >)
  • Export Merged: Creates a one row with a multi string geometry layer named:
      (M< U|D >) bdAstar: < source_id > to < target_id> BBOX(< bbox >)

pgr_bdDijkstra

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • pgr-v2.0, pgr-v2.1 & pgr-v2.2: Identifiers are converted to int4 type. costs are converted to float8
  • Buttons:
    • Preview: Draws in the canvas the area of the alpha shape
    • Clear Preview: Removes from the canvas objects generated with Preview
    • Export: Creates a one row per edge layer named:
      (< U|D >) bdDijkstra: < source_id > to < target_id> BBOX(< bbox >)
  • Export Merged: Creates a one row with a multi string geometry layer named:
      (M< U|D >) bdDijkstra: < source_id > to < target_id> BBOX(< bbox >)

pgr_dijkstra

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • pgr-v2.0: Identifiers are converted to int4 type. costs are converted to float8 , pgr-v2.1 & pgr-v2.2: Multiple source & target
  • Buttons:
    • Preview: Draws in the canvas the area of the alpha shape
    • Clear Preview: Removes from the canvas objects generated with Preview
    • Export: Creates a one row per edge layer named:
      (< U|D >) dijkstra: [< source_ids >] to [< target_ids>] BBOX(< bbox >)
  • Export Merged: Creates a one row with a multi string geometry layer named:
      (M< U|D >) dijkstra: < source_id > to < target_id> BBOX(< bbox >)

pgr_drivingDistance

pgr_kDijkstra(Cost)

  • Uses BBOX of the QGIS canvas to limit the edges in the query
  • pgr-v2.0, pgr-v2.1, pgr-v2.2: Identifiers are converted to int4 type. costs are converted to float8
  • pgr-v2.2: Function is being deprecated in favour of pgr_dijkstraCost which is not yet implemented in this plugin.

pgr_kDijkstra(Path)

pgr_ksp

pgr_trsp(Node)

pgr_trsp(Edge)

pgr_trsp(via edges)

pgr_trsp(via vertex)

pgr_tsp(Euclidean distances)
