In large spatial,temporal,and spatio-temporal databases,the concept of dimensions–time and space–is central and their efficient processing has always been a great concern.A Geographic Information System(GIS)is widely known for its efficient and sophisticated handling of the spatial databases;however,integration of the time domain introduces additional *** research is ongoing in this *** numerous approaches have already been proposed in the literature to address the time-related challenges in GIS community,such as the development of temporal GIS data models,this study contributes to these ongoing efforts through extensions to the Parametric Data *** database approaches(Parametric Data Model)have been developed to handle dimensional data such as space,time,belief,*** this study,the time dimension is of specific interest and we propose the integration of parametric approaches to GIS to absorb the temporal *** temporal processing of the data is done using parametric approaches that address the limitation of GIS to support temporal queries and temporal analysis of *** the AutoConViz tool,developed for spatio-temporal data modeling and visualization,results can be directly integrated into standard GIS software programs such as ArcGIS and further processed seamlessly along with and in a similar manner to other attributes.
