geospatial routing extension for PostgreSQL
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.
