Simulator application for generating GPS data for a vehicle roming around in a city.

This application uses the OSM Overpass API which offers read-only capabilities to the applications using the OSM database and providing web access to it. This application collects all the nodes in the vicinity of a city, gets the street nodes out of them and "drives" a vehicle along those streets. The application approximates the movement of the vehicle from node to node, on predefined intervals and regularly broadcasts its position.

1 Fetch City Nodes 2 For selected city node get all highway nodes of type way in supplied radius 3 Start at the first node of random way 4 Travel at speed close to the maximum with negative deviation for randomness 5 Calculate the distance of the way first - last point. This is needed for interpolating. 6 On end node turn at random joint road and repeat steps 4 - 7 7 If there's no joint road, turn back
