Parallel computer system utilization in geographic information systems

Present times can be defined by growing amount of data and information as well as growing complexity of data flows. In order to process this amount of data and information, there are efforts of development of specialized systems to process variety of geographical data - geographical information systems (GIS). GIS systems are foremost intended to archive data, but they are also able to solve some specific tasks, e.g. modeling of beneficial component distribution in mineral deposits. Geological phenomena modeling using GIS depends on correct interpretation of large amount of data acquired by measurement and observation. A single processor computer has found its performance limits. Thus, parallel computers take place in these exacting computations. Parallel computing requires special hardware and software support, but once it is correctly used, it surpasses performance of single processor computers. Multiprocessor systems encompass mathematically highly exacting visualization and modeling methods (e.g. geological objects modeling in geology) in few minutes or seconds instead of days or hours when using single processor computer.
