| Abstract: | This paper analysed some principles and methods of the regular grid terrain data,discussed how to construct the pyramid model of the regular grid terrain data.Then it completely discussed the principium,the methods and the implementing process about visualized editing of the RGD and studied the spread of the editing result from the edited data layer to the other layers of the pyramid model in all-around especially.At last,it gave a realization about the visualized interactive editing of the RSG based on pyramid model by the one point editing and the area editing. |
