This paper discusses the accuracy of spatial data estimated by areal interpolation. A stochastic model is proposed which represents areal interpolations in diverse geographic situations. The model is used to examine the relationship between estimation accuracy and the spatial distribution of estimation error from a theoretical viewpoint. The analysis shows(More)
This paper analyzed the accuracy of count data estimated by the point-in-polygon method. A point-in-polygon interpolation model was proposed which was based on a stochastic distribution of points and the target zone, in order to represent a variety of situations. The accuracy of estimates was numerically investigated in relation to the size of the target(More)

This paper analyzes the accuracy of count data transferred from a zonal system to an incompatible zone through the areal weighting interpolation method. To treat a variety of situations in a theoretical framework, stochastic models representing areal weighting interpolation are developed. The relationship between the accuracy of estimates and the size of(More)
