| Abstract: | D GISs were developed simultaneously in the late 1980s in a number of different disciplines.The development of these 3D GISs can not yet meet all needs for new representations and analytical tools in 3D environments.In this paper,the data structures,especially solid_based data representations are introduced.Then,a typical object_oriented data model is put forth to show a new data model.And at last,two data access methods are proposed to make the data model clear. |
