The amount of data required to meet various decisions is increasing steadily. Due to innovative information technologies this data can be structured and made available with fast access.
Geographic Information Systems (GIS) Today the elaboration of defined analyses without spatial allocation is nearly impossible. Communal infrastructures for sewage discharge, water and energy supply are connected almost completely with basic data from land surveys. The efficient application of this data is done successfully with the help of geographic information systems.
Geographic data can be handled individually with desktop-GIS or multidisciplinary by internet- or intranet-GIS-solutions.
