Pgdijkstra Routing Module
Pgdijkstra is a PostgreSQL module, for performing shortest path queries based on the Dijkstra algorithm
CartoWeb uses this module in the routing plugin to find the best path between two points, but it can be used outside of CartoWeb3 in stand-alone, for geographical or non geographical routing queries.
Documentation is provided in the README file. License: GPL.
This module is bundled inside the CartoWeb archives, in the contrib/pgdijkstra directory. Latest version is available with the CartoWeb CVS version.Windows version is available. See the Pgdijkstra Win32 page
Vertex Simplification Program
Generally, vectorial maps have a large number of points. Since they are really accurate and detailed, they required sometimes a few seconds to be displayed. This program simplifies maps by deleting vertex using a polyline simplification algorithm.
