LINK LEVEL WIND FACTOR COMPUTATION FOR EFFICIENT DRONE ROUTING USING 3D CITY MAP DATA

Embodiments include apparatus and methods for determining link level wind factors and providing routes for drones based on the wind factors. At least a portion of the route corresponds to airspace above a road network. Wind factor values are assigned to a range of altitudes of drone air space above a road link of the road network based on a wind model and stored in a database. The wind model is applied to a location based on wind condition data and three-dimensional (3D) features from 3D map data associated with the location. The route is optimized based on the determined wind factors.
