O článku:

This paper introduces and evaluates some geographical data transformation methods which allow data allocation from spatially inconsistent zonal systems. The basic and simplest transformation method – areal weighting – is compared with complex techniques which use auxiliary information to improve the results of the interpolation process. Such auxiliary information is the length and type of road segments, the node counts in street networks and the class of urban fabric pursuing the CORINE land cover nomenclature. For comparison, different data types were used. Apart from the usually estimated variable – population counts – it was the area of agricultural land. These variables were available for the 1991 census districts and were estimated for the system of functional urban regions – FUR 91-B. The measures of global fit and spatial vizualisation of percent errors associated with all of the variables and methods were used to evaluate the results of estimation.
