METHOD AND APPARATUS FOR GENERATING DIGITAL ELEVATION MODEL

摘要

The present invention relates to a method and apparatus for generating a digital elevation model, wherein the method comprises the steps of: receiving a digital surface model, and mask data which includes information for determining a structure region to be removed from the digital surface model; dividing the digital surface model into a plurality of segments; determining each of the plurality of divided segments as a topography or structure on the basis of the mask data; and generating a digital elevation model on the basis of the determination result. The present invention corrects the determination of a region which is wrongly processed as a topography or structure in a process of generating a digital elevation model, thereby improving the accuracy and reliability of the digital elevation model. In addition, since it is unnecessary to excessively reduce the size of a processing window in order to improve the accuracy of a digital elevation model, it is possible to prevent excessive data processing, thereby improving the efficiency of system resources and promoting rapid data processing.
