距离度量关系分析是GIS空间分析的重要组成部分。本文在传统的距离度量分析方法数学描述基础上,引入面向对象数据模型,将地理实体抽象为空间对象,用空间对象代替几何元素,给出了基于面向对象数据模型的地理实体距离度量关系分析方法的数学描述以及算法的实现过程。%Analysis of distance measure relations is an important part of GIS spatial analysis .Based on the traditional mathematical description of distance measure method , the paper introduces object-oriented data model , abstracts geographic entity to spatial object which is instead of geometrical element .It gives the mathematical description and designs the realization process of method of geo -entity distance measure relations based on object -oriented data model.
