GIS and the dynamic phenomena modeling

Dynamical GIS For GIS, as a tool of decision support, it is very important to incorporate and to be able to use the dynamics of objects and phenomena starting from the temporal database creation and finishing by the development of new approaches and methods focused on the analysis of the objects and phenomena around the temporal axis. Dynamically oriented system tends to introducing of the temporal state and development of the objects and phenomena. Mathematical model considers usually simplified assumptions and estimated parameters to be able to fulfil some practical conditions of the definite task domain. Using of this model for different range of tasks, it effects in the significant inaccuracy in different parts of evaluation and trend analysis and interferes with the stability of the model. Apart from the fact that there are many difficulties with dynamics, modelling the geo-information processing tends to the temporal GIS (Claramunt, Thériault 1996; Claramunt et al. 1998). It means the system that has to its disposal not only the thematically oriented static picture of the service area but it will be able to use the regularly and systematically processed data from the point of landscape development , trends evaluation and behaviour modelling of all objects and phenomena and map temporal consequences. Thanks to the Mobile Internet GIS, Mobile Web Map Services and Mobile Web Analytical Services that facilitate the acquiring of data, it is much easier to monitor and map the temporal states of the objects and phenomena. It is a new solution that offers mobile Internet access to the data including their updated versions. Abstract: Different aspects of the dynamic or temporal of GIS are very frequently discussed and we can register new approaches and applications in this field every week. This paper analyses the possibility of the selected approaches to contribute to the temporal data processing and gives the overview of the most basic ones. The author presented part of these results also at the Agrarian Perspectives Conference 2005 in the applied informatics session. Abstrakt: Různé aspekty dynamického nebo temporálního GIS jsou v poslední době velice často diskutovány a nové pří-stupy a aplikace se objevují každý týden. Tento příspěvek analyzuje možnosti vybraných nástrojů přispět ke zpracování temporálních dat a věnuje se některým aspektům těch nejzákladnějších.
