ÜBER EIN LANDINFORMATIONSSYSTEM FÜR DIE AUFGABEN DER ENTWÄSSERUNG

Starting with the terrain information of traditional design, requirements to the geo- graphical information systems of CAD technology are outlined. The structure of a geographical information system for LAD, means and methods of data acquisition used in design, experi- ences of development are presented. Generalizing experience in developing the CAD system, the applied hardware, pos- sibilities and limitations of given system, are given, outlining the interactive design process of the drainage network, and the applied digital models.
