摘要：The modern digital cartography, represented by numerical cartography, digital elevation models (DEM, DTM, DSM), orthoimages or the same like photo textured on DEM, is the metrically correct and highly descriptive system on which integrate any other source of information. These three-dimensional models in dynamic GIS can provide an interesting tool for the environmental and territorial data management. Aim of this research is to set up procedures for generating a three-dimensional map with maximum characteristics of description and the best accuracy, in order to be over the bi-dimensional GIS mapping system. DTMs, orthoimages and their 3D models overlay are performed by softwares dedicated to digital photogrammetry (ER Mapper, Surfer) and CAD designs (3dStudio Max, AutoCAD 2000). Successively these representations have been elaborated within the GIS system for a series of different themes and queries, which can be of a great support for a decision system. The use of geographic computerised system is fundamental to acquire, manage and revise all sort of information. This work shows how to create a complete, as far as the cartography is concerned, three-dimensional database within the GIS system. Digital sensor derived images, or digitalised images, remote sensing acquired, or any other spatial referred qualitative or quantitative data can be used as data for the application of new methodologies and new procedures for the cartographical elaborations and their representations. Their final products, or the intermediate ones, are easily managed by very well and worldwide known systems, such as the GIS one
