ABSTRACT
Geographical Information System (GIS) is a popular information system for processing spatio-temporal data. It is used as a collaborative platform for visualization, analysis and computation involving spatio-temporal data. GIS is the name for a generic information domain that can process spatial, a-spatial or non-spatial and spatio-temporal data pertaining to the objects occur in topography, bathymetry and space. It is used for many decision support systems and analysis using multiple criteria. It has emerged as one of the important systems for collaborative operation planning and execution using multi criteria decision analysis involving land, sea and air. The popularity and usage of GIS can be judged by the large amount of literature available in the form of books [21], [31], [20], [12],[25], [4],[8], [57], [41], scientific journals such as the International Journal of Geographical Information Science, Cartography and Geographic Information Science, Computers and Geosciences, Journal of Geographic Information and Decision Analysis, Journal of Geographical Systems, Geoinformatica, Transactions in GIS, The Cartographic Journal, The American Geographer, Auto-Carto, Cartographics and the research publications from academic and scientific organizations. From these research literatures the growing trend in design of algorithms and novel computing technique for visualization and analysis of spatio-temporal data is evident.
