摘　　要：三维空间分析是3D GIS成熟的一个重要标志,也是当前业界的研究热点之一。叠置分析作为空间分析的一种最常用、最基本的功能,其实现具有重要的现实意义。通过探讨基于TEN的三维叠置分析,分别给出了点与体、线与体、面与体、体与体的叠置分析方法。该方法实现了将复杂的体先分解为TEN,然后再将各类实体与TEN进行叠置分析。3D spatial analysis is an important sign for the maturity of 3D GIS,and it is also a hot in the current industry overlap analys as the most commonly used and the most basic function,and its implementation has important practical significance.The paper discusses 3D overlap analysis based on TEN and proposes the overlap analysis method by point and body,line and body,surface and body,body and body.The method decomposes complex body into TEN firstly,then carries out overlap analysis between various features with body,which has certain innovation.
