基于回溯地理编码方法的人口研究

Population Research Based on Retrospective Geocoding

文中的目的是描述在人口研究上使用多相地理编码回溯建立地理信息系统的方法。介绍了回溯建立一个地理信息系统的挑战并提出了提高地理编码成功率的实用技巧。使用4800个人的详细情况作为基准数据,在多相过程中完成这些人的地理编码。经过初步删除不能地理编码的地址(38例),使用Arc GIS 96%地址被编码。在这些样本的记录中使用数据抽象的回溯方法,利用地址的核查,除19个地址外,成功地取得了所有地理编码,近99%(4743例)被地理编码。

The main purpose of is to describe the method of using the multiphase geocoding to retrospectively create a GIS. It also introduces the challenge of retrospective creating a GIS and advances some practical tips that improve the success. 4800 people＇ s detailed in- formation was used as baseline data , finish this people＇s geocoding in muldphase process. Using Arc GIS 96% addresses were coded after delete the addresses which can not be coded. An interactive method using data abstraction from sample records, use of verification of existence of address, yielded successful coding of all but 19 addresses. Overall, nearly 99% of the addresses were coded.
