摘要
本文针对基于欧氏距离缓冲区分析在选址应用中的不足,将路径思想引入缓冲区分析中。以商场选址为例,分析、定义了路径时间、出行时间的概念和数学模型,并在此基础上提出了基于出行时间的缓冲区分析方法,并给出了实现算法和分析实例。结果表明,基于出行时间的缓冲区分析在选址分析方面有很大潜力。
In this paper, route conception is introduced to make up for the shortcoming of buffer analysis based on Euchdean distance in address choosing. And taking a shopping mall address choosing as an example, the paper discusses and defines the conceptions and mathematic models of route time and travel time in GIS. And then the buffer method based on travel time is put forward. At last, algorithm and analysis example of buffer analysis based on travel time are proposed. The results show that the buffer analysis based on travel time has great potential in address choosing analysis.
