grozin@gentoo.org Andrey Grozin sci@gentoo.org Gentoo Science Project An application for finding a route between two points using the dataset of topographical information collected by http://www.OpenStreetMap.org. This router uses a routing algorithm that takes OSM format data as its input and calculates either the shortest or quickest route between two points. To optimise the routing a custom database format is used. This allows the routing to be performed quickly after a modest one-off pre-processing stage.
