For naming:
- < U|D >:
- U = Undirected
- D = Directed
- < bbox > = xMin yMin, xMax yMax
- M = when Export Merged button is used
- < U|D >:
-
Information about the pgr-v2.2 is also included
- 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 tofloat8
-
pgr-v2.1 & pgr-v2.2:
pgr_drivingDistance
for one starting vertex is used.
-
pgr-v2.0: Identifiers are converted to
- 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 >)
- Uses BBOX of the QGIS canvas to limit the edges in the query
-
pgr-v2.0, pgr-v2.1 & pgr-v2.2 & pgr-v2.3: Identifiers are converted to
int4
type. Costs are converted tofloat8
- Buttons:
- Preview: Draws in the canvas the resulting path.
- Clear Preview: Removes from the canvas objects generated with Preview
- Export: Creates a one row per edge line geometry layer
- Export Merged: Creates a one row per path multiline geometry layer. Only one row is generated
- Layer name:
(< M >< U|D >) astar: < source_id > to < target_id> BBOX(< bbox >)
Example: pgr_astar from 2 to 3 on Undirected graph:
pgRouting versions | graph | note |
---|---|---|
v2.0 v2.1 v2.2 | pgr_astar has a bug | |
v2.3 | pgr_astar bug is fixed |
