On 3D GIS Spatial Modeling
|
Abstract:
3D Spatial Modeling is the key to 3D GIS, and is the basis of 3D GIS. All kinds of 3D spatial modeling methods are different according to the differences of modeling objects. Based on the difference of spatial modeling objects, 3D spatial modeling methods are divided into two kinds. One is Geographical Spatial Modeling, and the other is Geological Spatial Modeling. Based on the comparision and contrast of all the 3D spatial modeling methods, this paper also presents some key issues on 3D spatial data modeling.
