如何解决汇总统计数据来源之间的地理不兼容问题是影响许多国家研究人员的一个问题。随着最近英国人口普查数据量的增加,行政和选举边界以及为人口普查数据收集和统计产出目的专门界定的地区的边界都发生了相当大的变化。本文回顾了在不同的空间尺度的地理不一致的程度,并概述了一个基于网络的接口,实现了智能面积插值(dasymetric映射)算法,使人口普查计数的估计,以获得一致的空间单位对最近的英国人口普查(1981年,1991年和2001年)的发展。一个有限的访问用户试验已经进行,该文件说明了一个典型的用户查询,旨在估计1981年的人口计数在1991年的枚举区边界。本文的结论是考虑进一步发展的接口,其纳入现有的人口普查数据单位在英国提供的服务,其更广泛的潜力,解决地理不兼容的问题。
The issue of how to address geographical incompatibility between aggregate statistical data sources is one affecting researchers in many countries. The increased amount of data from recent British Population Censuses has been accompanied by considerable changes in both administrative and electoral boundaries as well as those of areas specifically defined for census data collection and statistical output purposes. This paper reviews the extent of geographical inconsistency at different spatial scales and outlines the development of a web-based interface that implements an intelligent areal interpolation (dasymetric mapping) algorithm that enables estimates of census counts to be obtained for consistent spatial units across pairs of recent British censuses (1981, 1991, and 2001). A limited-access user trial has been carried out and the paper illustrates a typical user query that seeks to estimate 1981 population counts in 1991 enumeration district boundaries. The paper concludes by considering further development of the interface, its incorporation into the services provided by existing census data units in the UK, and its wider potential for addressing the issues of geographical incompatibility.
