pgRouting

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 Quantum GIS 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.
