Abstract

Abstract: This paper focuses on analyzing the three dimensional location definition（3D-LD） of a object，which sets buildings as its three dimensional background.This essay aims to study the characteristics of 3D-LD.Meanwhile，it mainly discusses on the basic structure of 3D-LD，analyzes the method of making the major 3D-LD module，gives the method of organization of three dimensional.Also，it offers an appropriate software programming technology solution to 3D-LD system.

Key words: Three Dimensional Location Definition（3D-LD）, spatial data, GIS, MIS

摘要： 对以建筑物为三维背景空间的物体对象的3维位置定义（3D-LD）管理进行了深入分析，研究了3D-LD数据特征，分析了3D-LD关键要素模型的生成方法，给出了3D-LD三维场景的两种组织方式，并最终给出适合当前软件编程技术的系统实现方法。
