ABSTRACT
The GIS (Geoinformationsystem) is meant for collecting, analyzing and representing all data that concern technical and administrative installations to be found on a limited land area as well as data on georelated disciplines (drillings, types and magnitudes of mineral and metal resources, phreatic or deep water resources, pollution density etc.). After discussing general aspects of GIS, the paper presents a short history of it, discusses theoretical concepts, functionality, usage and advantages of the system. A special chapter deals with the influence of GIS on maintaining the quality and quantity of underground waters used as drinking water, in industry and agriculture. The last chapter presents proposals to introduction the GIS in the curricula of civil engineering and geologic faculties.
