顾及矿山特性的三维GIS数据结构与可视化

3D GIS Data Structure and Visualization Based on Mine Properties

在对几种可以应用的三维数据结构进行分析的基础上 ,指出 TIN、三维栅格、八叉树、三维矢量、TEN、面向对象等数据结构可以实现对不同特点矿山实体的三维表达与模拟 ,而三维混合数据结构则是最有效的 .三维数据结构是实现三维可视化包括三维景观模拟、三维数据场可视化、虚拟 GIS应用等的基础 .

Based on the properties of mines, the demands of GIS applications in mines and the analysis of some feasible 3D data structures, it is pointed out that TIN, 3D raster, octree, 3D vector, TEN, object-oriented data structure can be suitable for different conditions, and hybrid or integrated data structure is the most efficient. 3D data structure is the basis of 3D visualization including 3D landscape simulation, 3D data field visualization and virtual GIS applications.
