GIS Tools

pgRouting extends the PostGIS/PostgreSQL geospatial database to provide geospatial routing and other network analysis 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.

pgRouting is available under the GPLv2+ license and is supported by a growing community of individuals, businesses and organizations.
