| Abstract: | Electronic sand table,some called digital sand table or virtual sand table,is contrast with traditional material sand table model. Unlike material sand table,electronic sand table is new high-tech product with in-tegration of computer application,Geographical Information System,virtual reality and multimedia. It can give users a real-time and interactive operation circumstance. With the development of computer technology,material sand table is now transmitting into electronic sand table. First of all,this paper introduces the design and realization scheme of electronic sand table system for the west side of Taiwan Straits. Then,the key technique of the technical scheme for electronic sand table,such as data processing,terrain modeling,feature matching,is introduced in details in this paper. Finally,based on digital elevation model (DEM) and satellite remote sensing image,the electronic sand table system for the west side of Taiwan Straits is made under the platform of MapGIS. |
