PgRouting Layer is a plugin for QGIS that serves as a GUI for pgRouting - a popular routing solution for PostGIS databases.

Currently, it supports pgRouting's following functions.

• Anita Graser quick Start

pgRoutingLayer for 2.1 Supported functions

For the following table.

• All pgRouting functions from version 2.0 only support integer on identifiers and float8 on costs.
• Starting from 2.1 some functions are able to use ANY-INTEGER for identifiers and ANY-NUMERICAL for costs, indicated with ANY.
• Some new functionality have one/many to one/many options like pgr_dijkstra. Indicated with many
• Some functionality has being deprecated, indicated with dep
• For this plug-in pgr_alphashape is based on the results of pgr_drivingDistance with one starting point
• The plug-in adjusts automatically to the signature of the pgRouting version installed in the connected database.
• the table includes the status if used with 2.2
