摘要
A method for generating a three-dimensional terrain model while using object-oriented vector data that contain supporting points, which describe the terrain, of position values indicating at least the cartographic position, and of elevation values that indicate their height or depth with regard to a reference level. The aim of the invention is to obtain a stable method that automatically ensues without human interaction. To this end, the elevation values of the supporting points are extrapolated within a uniform grid, and all extrapolation values are subjected to a weighted interpolation.
