This tutorial is about OsmSharp and can be used to calculate simple point-to-point routes and saving them als a GPX-file. All routing will have to be done using the Router class. It encapsulates all the routing functionality. A datasource can be created using a regular osm file.
The code for tiny tutorial can be downloaded here.
- Import Osm.Core, Osm.Data, Osm.Routing, Tools.Core and Tools.Math into a new project.
- Use the following code to calculate one small point-to-point route.
// create a router from an osm file. Router router = Router.CreateFrom(new FileInfo("demo.osm")); // instantiate route end coordinates. GeoCoordinate location_from = new GeoCoordinate(51.26565,4.7777); GeoCoordinate location_to = new GeoCoordinate(51.2741,4.79795); // resolve the end points and link them to the road network. ResolvedPoint from = router.Resolve(location_from); ResolvedPoint to = router.Resolve(location_to); // calculate the route. OsmSharpRoute route = router.Calculate(from, to); // save the route as a GPX file. route.SaveAsGpx(new FileInfo("demo.gpx"));
