The technological convergence of work station capabilities and GIS computational requirements
This paper examines the current computational requirements for monitoring less favoured regions of Europe by the use of remote sensing, integrated with geographical information systems. In particular, the memory requirements and processor speeds are estimated for various types of geographical data processing, involving both high resolution satellite imagery and digital map datasets plus terrain models. The implications of different data formats (raster, vector, and quad-tree) are considered in this context. The features of the most recent and powerful graphical workstation systems are discussed, and their usability for GIS applications at different levels of spatial complexity is assessed. A review of the general trend in workstation evolution is also presented as a means of estimating the possible use of workstations for monitoring environmental features from satellites on a Europe-wide (rather than regional) scale.
