The Ministry of the Environmental of the Slovak Republic and Ministry of Agriculture of the Slovak Republic and their institutions are in charge of creating information systems of the Environment for several years. These systems are aimed to collect, store and disseminate information needed for spatial assessment and planning. At present data collection and processing of each environmental component is realized separately. It is a consequence of different funding and of differences in mapping approaches, equipment and skills of personnel. In short contributions the information is presented on data acquisition methodology, the use of the secondary data sources, applied software, public access to different databases and possibilities of their application. Up to now there is lack of standardization in applied approaches. The aim for close future is a mutual interconnection of different databases, because a functional environmental information system is a definite condition of the effective management and protection of each region.
