pgRouting extends the PostGIS / PostgreSQL geospatial database to provide
|
|
geospatial routing functionality.
|
|
|
|
Advantages of the database routing approach are:
|
|
|
|
* Data and attributes can be modified by many clients, like QGIS and
|
|
uDig through JDBC, ODBC, or directly using Pl/pgSQL. The clients can
|
|
either be PCs or mobile devices.
|
|
* Data changes can be reflected instantaneously through the routing
|
|
engine. There is no need for precalculation.
|
|
* The "cost" parameter can be dynamically calculated through SQL and its
|
|
value can come from multiple fields or tables.
