CAD systems are oriented towards modeling individual man-made objects and structures with relatively high level of detail, so the data stored covers small areas with huge amount of information. ...
As a case study for explaining the problem, we use comparison of two main groups of software tools covering this area GIS and CAD systems -and the posibilities of their integration. ...
As would be seen the object-oriented approach provide a number of mechanisms to model real objects in a natural way.
3D GIS data management As a last issue we have to describe the 3D GIS data management ...
