摘要
三维模型的空间分析是 3DGIS的重要内容 .本文研究了三维模型的空间坐标查询、任意两点间的剖面绘制、空间距离量算、面积量算、坡度 /坡向分析等功能 。
The Spatial Analysis of 3D-Model is an important content of 3DGIS. Research is made on the functions about querying spatial coordinate of 3D-Model, drawing section plane between arbiter two points, calculating space distant, calculating area, grade/slope-direction, and etc. It specially has important meaning for base development of mini-project of 3DGIS.
