QGIS Python Plugins Repository
Plugin: Routes and Zones
Plugin RaZ is a wrapper for standard network analysis library in QGIS. Allows you to calculate a routes and zone of transport accessibility from one set of points to another set of points.
On the basis of user data, the plug-in solves two problems. The first task is to build routes from one group of point objects to other point objects group, subject to specified limits on the length of the route. To speed up the process, using the previously calculated return routes and recorded routes, previously ignored because it exceeded the length restrictions. The second task is the calculation of the areas transport accessibility of the specified length around an arbitrary group of point objects. Sample QGIS project file is in plugin subdirectory "sample-data". Use interface illustration file is "sample-data/illustration/sample use.png".
