GIS中的地图叠置操作经常伴随着不兼容的分区系统之间的数据传输。有各种数据传输方法，称为区域插值方法。然而，任何插值方法都涉及数据传输中的错误，因为关于重叠区域中空间对象分布的信息不足。本文提出了面积加权法传递计数数据误差的概率模型，并分析了源带系统、目标带与GIS中记录计数的空间对象分布之间的关系。理论和实证研究结果表明。
Map overlay operation in GIS is often followed by a data transfer between incompatible zonal systems. There are various methods of data transfer which are called areal interpolation methods. Any interpolation methods, however, involve error in data transfer because of insufficient information about the distribution of spatial objects in overlaid zones. This paper proposes a probabilistic model of the error in count data transferred through the areal weighting method, and analyze the relationship among the source zonal system, target zone, and the distribution of spatial objects whose counts are recorded in GIS. Both theoretical and empirical findings are shows.
