Road Surface of a three-dimensional Landmark

摘要

The invention relates to a method for processing a 3-dimensional landmark (60) providing a 3-dimensional representation of a 3-dimensional real world object located at a predefined geographic location, the method comprising the steps of providing a data set containing the 3-dimensional landmark (60), determining a largest continuous horizontal surface (62) of the 3-dimensional landmark, and storing the determined largest horizontal surface (62) as road traffic area of a road network used by a user when moving on said object.
