pgRouting

GIS Tools

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.

Core Features

pgRouting provides functions for:

• Shortest Path Dikstra: routing algorithm without heuristics
• Shortest Path A-Star: routing for large datasets (with heuristics)
• Shortest Path Shooting-Star: routing with turn restrictions (with heuristics)
• Traveling Salesperson Problem (TSP)
• Driving Distance calculation (Isolines)
