| Abstract: | Modeling in levels is a new way to instruct electric sand table, including terrain modeling, buildings extraction, complex object modeling, terrain and object fusion, and so on. And it analyzes the excellence of this method. This method has been used in the modeling electric and table of CSU. It brings forward the matter needed reaching and settling next step, then improves efficiency of modeling 3D electric sand table. |
| Keywords: | electric sand table digital elevationmodel (DEM) modeling buildings extraction |
