Abstract

This study assesses the degree to which current requirements for land resource analysis can be met using the technology of geographical information systems (GIS). The author finds that a major reason behind the shortcomings of many existing systems in terms of performance, flexibility and integration of data appears to be the methods of structuring data. In view of this, the potential of hierarchical data structures are studied as a means of overcoming many of the shortcomings of vector and raster structures. The structure and operation of a pilot GIS which uses a hierarchical data structure known as a linear quadtree is described and used in a series of studies to assess its potential. Results show that GIS based on linear quadtrees have significant potential for land suitability classification and resource modelling in the UK. Remotely sensed and cartographic data can be synthesised to form comprehensive resource inventories. -from Author
