摘要
地理编码在GIS中的应用和研究中具有重要的意义。现有的GIS软件一般都有地理编码的功能 ,但在实际的操作中 ,都存在一些不足 ,主要有两个方面 ,一是不能基于多个参考主题同步匹配 ;二是基于地块的匹配 ,相同地址的记录定位后产生重叠。作者利用Avenue语言对ArcView中的地理编码进行改进 ,开发了一个新的地理编码模块 ,并应用在上海市商业服务业普查数据的地理编码中。论文介绍了该地理编码模块的算法。
Geocode plays an important role in application and study of GIS. The existing GIS software usually has the geocoding function . But there are some shortcomings in practical application, which mainly have tow aspects, one side is that geocode can’t base on multiple theme synchronizedly . On the other hand the records with same address will be overlapped after geocoding based on region. The developed a new geocoding module by avenue to improve the function of the geocode in arcview, which was applied in geocode of shanghai business&service data.This paper introduce the algorithm, realization and application of the geocoding module.
