Geographic information systems (GIS) are routinely used to integrate different layers of geospatial information for spatial analysis and decision making. Such an integration often involves data of geospatial attributes available at different geographical units, e.g., administrative zones versus pixels of remotely sensed imagery. What is required in such cases is a transformation of attribute values from one existing spatial partition to another, that is, a change of the geographical units over which the original data were acquired with an associated change in the actual attribute values reported. In public health applications, for example, socioeconomic data reported over census tracts must be integrated with disease data available over different administrative reporting zones, to assess disease risk at increasingly finer spatial resolutions. Similarly, in remote sensing applications, reflectance data recorded by...
