Geographical information systems and urban management

GIS represents a working technique more and more useful for contemporary world both in the field of theoretical research and in very many practical activities. In fact, GIS introduction, their storing, interpretation and analysis is done by means of the computer, the result being mainly the ability to see some complex information, spatially differentiated in comparison to real geographical coordinates. Secondly, GIS techniques allow combining information of different types (figures, images, maps), hardware and software components, all being under the direct coordination and determination of the human component, in order to make analyses and correlations of great complexity. Management of urban space requires spatial accurate information from the design of applied changes of urban lands and survey of these changes is also important for users and urban managers. For this purpose, GIS has been useful tools for scientific analysis which gives information about changes and converge of ground surface to the urban managers for its optimal use
