Issues of GIS data management
The paper deals with current issues of spatial data modelling and management used by spatial management applications. 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....

The paper deals with current issues of spatial data modelling and management used by spatial management applications.
