Using spatial and 3D analysis instruments in a G.I.S. project [articol]

Abstract

The GIS technology is used in all fields for which the spatial information is relevant, that means in all fields that use the geographical map for stocking, analyzing and representing the data which are processed. No matter what is the field, any GIS application includes a spatial data base (a digital map) and a soft which exploit these data bases. The digital map must contain the spatial data specific to any field whose it is designated to this application. In order to furnish some useful information, this data base must be actual, which means it must represent correctly the terrain (geographic space) that is always under changing. This exploitation soft is made from many functions of analyzing the spatial data contained into the digital map and of visualizing the resulted information, specific to the application field.
