Zusammenfassung:The present invention relates to a method for generating a digital representation of a physical terrain, comprising the steps of reading data of a digital terrain model including raster points having coordinates including a height coordinate that indicates height values of the raster points, determining differences between the height values of adjacent raster points of the digital terrain model, storing only those raster points with height values that differ from the height value of at least one adjacent raster point by at least a predetermined threshold and calculating three-dimensional B-spline surfaces interpolating the stored raster points.
