DOM AND DEM SYNCHRONIZATION EDITIONG AND UPDATING METHOD BASED ON GEOMORPHOLOGICAL CHANGE DETECTION
Keywords: DOM, DEM, Geomorphological Change Detection, Synchronization Editing and Updating Method
Abstract. Aiming at the deficiency of the existing DOM and DEM production modes and the networking and automation requirements of the information mapping production system, a method of network-based simultaneous editing and updating of DOM and DEM based on geomorphological change detection was proposed, a set of rapid update technical processes for changing regions were formed, and the DOM and DEM network rapid editing and updating platform was developed. The technology process is based on network parallel environment to achieve network task distribution and multi-person synchronous editing production, and the production efficiency of DOM and DEM is greatly improved.
