An extensive surface model database for population- related information: concept and application

Information technology has had a substantial impact on methods of geographical study. Although this varies between different application fields, effective use of the new technology requires careful consideration of the underlying concepts of geographic data representation. Here, an improved data model is described by means of raster techniques to represent population-related data in the form of surfaces. This type of model is seen as having broad applicability to the representation of socioeconomic information taken, for example, from a population census or from residential postcoded records. In this paper an extensive application of this approach to large geographical scales is described by reference to Britain, and suggestions are made as to the advantages of such a data model for socioeconomic visualisation and analysis.
