Techniques for modelling population-related raster databases

In this paper the refinement and application of a technique for the generation of surface models of population and related information are examined. With use of this technique the efficient generation of geographically extensive, high-resolution surfaces is described. The resulting database facilitates a range of improved spatial analyses. Some of these are more flexible means of accomplishing conventional tasks, such as the computation of incidence rates and the estimation of population for nonstandard areal units. Additionally, surface concepts are able to support innovative techniques, such as the identification and characterization of discrete settlements. Applications are described which demonstrate the range of possible analyses.
