Elaboration of geological information using GIS brings also some serious problems. Correct and effective analysis of the complex system of surficial and subsurficial objects requires whole palette of specific data, which are typical for problematics of geology (e.g. precise location of data in real 3D co-ordinates, common variability of geological objects and phenomena in the space and in the time etc.). Traditional GIS technologies are oriented especially on administration and management of 2D data. It is possible to create in such systems (ArcInfo, ArcView, MapInfo) the whole palette of maps for specific purposes. Geological GIS require data analysis and elaboration in a 3D space. Consequently, it is later possible to solve some problems connected with simulation of geological phenomena and also to solve some problems of geological prospection.Simulation of spatial processes and objects requires empirical data, which are maintaining the essence of natural system. Spatial analysis includes quantitative and qualitative evaluation of discrete and continuous geological data in a small and also in a big scale. GIS contains sub-systems for input, management and output of data. This subsystems arose as an answer for the need of visualization of complicated spatial databases. These subsystems are designed for description of causal presence of geological phenomena as a function of time and for analysing of spatial relations of variables. Animation of maps was designed as a kind of visualisation of time-and-spatial variables, panoramatic views and spatial simulation. From these reasons geological GIS are as called as Geoscientific Information Systems (GSIS).
