开发了地理单位之间数据转换的概念框架。它用于检查地理转换表的构建，该表有多种形式，并且最近在英国受到政府对邻里概况分析的重视而受到刺激。当不同地理系统的边界重叠时，数据从一个系统到另一个系统的转换涉及近似。在这种情况下，使用非层次地理转换表，数据转换相当于统计综合估计。在构建地理转换表时以及在重叠地理区域之间转换数据时的近似值中都会出现错误。通过地理转换估算数据时的错误类型由各种英国示例的经验测量进行了补充。使用源单元数据的加权和的数据转换被证明比将整个源单元的数据分配到单个目标单元更准确。数据转换估算的质量测量是必要的，并且已提出。版权所有 © 2002 John Wiley & Sons, Ltd.
A conceptual framework for conversion of data between geographical units is developed. It is used to examine the construction of geographical conversion tables, which have taken many forms and have recently been stimulated in the UK by government emphasis on neighbourhood profiling. Where boundaries of different geographical systems overlap, then conversion of data from one system to another involves approximation. In this case non-hierarchical geography conversion tables are used and data conversion is equivalent to statistical synthetic estimation. Errors arise both in the construction of geographical conversion tables and in the approximation when converting data between overlapping geographies. A typology of errors when estimating data by geographical conversion is complemented by empirical measurement for a variety of UK examples. Data conversion using weighted sums of source unit data is shown to be more accurate than the allocation of data for whole source units to single target units. Measures of quality for estimates from data conversion are necessary and are proposed. Copyright © 2002 John Wiley & Sons, Ltd.
