Topic of this paper is the usage of the multidisciplinary GIS platform for Design of Building Structures and GIS platform for education at the Brno University of Technology (BUT). The GIS technology has been made use of at BUT Brno in a limited extent since as early as the 90's, but as it was out of acceptable price range the utilization in greater extent was not possible. With the support of research projects the GIS platform became part and parcel of accredited study programmes at BUT Brno three years ago. Current informatics infrastructure was completed with necessary systems Geomedia 6.0 (Intergraph) and Arc/Info (ESRI), which are commonly widespread platforms. On initiation of Institute of Geodesy, Faculty of Civil Engineering GIS data warehouse has been established for the needs of tuition at BUT Brno, it contains all types of basic maps of CR and other types of data (ZABAGED, Orthophoto, BM - CR of various scales, cadastral maps, purpose-built maps, historical maps, special data - laser scanning, DMT, satellite data and others) in the localities of interest. The data warehouse is continuously supplemented. A part of GIS platform is a catalogue of maps containing fragments of cadastral, civilian and military map works since 1825 till now.
Hardware for the platform is the server HP Proliant DL380 G5 rack with 2x Quad-Core Intel Xeon Processor E5440 (2,83 GHz, 80 Watts, 1333 FSB), 32 GB RAM memory PC2-5300 Fully Buffered DIMMs (DDR2-667) with Advanced ECC, disc space 8x 146 GB HDD SAS 10000 rps, Hot-plug and net interface 2x Gbit LAN. ArcGIS requires database connectivity. As the university information system and additional university applications are in the long term based on Microsoft technology, in this case the platform MS SQL 2008 in 64 bits version was also used.
On the basis of standard multidisciplinary GIS platform the interests of several individual branches and worksites has been succeeded to be integrated e.g.: branch of Geodesy and Cartography (application in range of real estate cadastre, geology and geodynamics, GIS of small municipalities and others), branch of Water Management and Water Structures (solution in the field of hydrology), branch of Construction and Traffic Structures (GIS in traffic) and others. Informatics infrastructure is guaranteed at Faculty of Civil Engineering by Institute of Computer Aided Engineering and Computer Science, within the BUT by Faculty of Information Technology. The software solution of tasks in Open-GIS systems (Grass) ranks among contemporary trends. This article will be completed with demo results of hitherto solved tasks in the GIS sphere at the Institute of Geodesy, Faculty of Civil Engineering, BUT. Current civil constructions and structures are designed as optimized from a lot of aspects. Information integrated within the information system enable when proportioned to take into account even the influence of the outer conditions resulting from the geographical position and there out arising parameters e.g. the amount of rainfall, the speed and the direction of the wind, length of sunshine intensity, geology etc. The platform provides database enabling to simulate different variability of practical conditions of project assignment in the region. Data structure provides localized and geospatial data from global or regional character up to the detailed information of a particular cadastral allotment.
Modern decision making in flood risk management is based on theoretical means which make possible objective forecasting of flood consequences, both qualitative and quantitative. Necessary tools for the practical implementation of the risk analysis methods in floodplains are the contemporary mathematical models of water flow in the inundation area linked to a powerful GIS. The main task of GIS is to administer the input data, to analyse them and to present the results.
