Geographic information systems (GIS) have been seen as an important enabling technology in the integration of satellite remote sensing and more conventional forms of land use information. The development of GIS has closely followed perceived application needs in physical geography and led to the implementation of numerous digital databases for land resources management. However, data relating to the human population and its socioeconomic characteristics have been poorly integrated with these advances for a number of reasons. Geographic information processing in the social sciences has tended to lag behind the development of systems for physical applications and, at a more fundamental level, there are important differences in the way in which socioeconomic phenomena have been conceptualized and modelled. Nevertheless, an understanding of the distribution and characteristics of human activity has an increasingly important role to play in many questions relating to the management of the physical environment. This paper seeks to demonstrate the application of some developments in socioeconomic analysis using GIS to integrate conventional physical resource data with socioeconomic information in the context of land use planning. These involve the modelling and analysis of population information in a raster GIS environment, incorporating contemporary geodemographic techniques and providing valuable information on the analysis of settlement and neighbourhood patterns and the distribution of residential, commercial and industrial activities.
