The classic and digital cartography, information sources for GIS applications

The spatial localized information and the possibility of its real-time updating has a far bigger impact both in the interdisciplinary studies and research and in the earth forms' reprezentations and modeling, along with the GIS technology of the information integration and analysis. Allow for the carrying out of complex studies on the land numerical models. In order to perform a land numerical model, the information is acquired from the axistent plans, there after is processed and integrated in the GIS system. The model obtained is used in the hydrological study and analisys of a drainage basin.
