摘要： 基于距离的分析是GIS中的一项基本空间分析功能，目前该分析主要是基于二维的，对三维空间的距离分析研究则较少。对基于三维栅格的距离分析进行了研究，提出了基于三维栅格的最短距离算法，并把该算法应用于非均质的三维缓冲体的生成。
关键词: 三维GIS, 栅格, 最短距离, 缓冲体
Abstract: The analysis based on distance is one of the basic spatial analyses in the GIS.This analysis is applied mostly in 2D GIS by now，and the research on this analysis is little.This paper studies the distance analysis based on the 3D raster，and proposes an algorithm about the shortest distance.At the end of this paper，this algorithm is applied for the the 3D heterogeneous buffer-generation.
Key words: the three dimension GIS, raster, the shortest distance, buffer
