in the alphanumerical data-base and production of 
thematic maps satisfying specific requirements; 
- Building of queries, simple as well as complex, linking 
the alphanumerical data with the positional information; 
- Support in the management of specific areas, according 
to their peculiarity, and production of printed maps for 
local use; 
- Data exchange capacity with comparable data-bases 
held by international, national or local territorial 
Agencies. 
- System architecture with client/server accessibility at 
the local level (National Park administration) or by 
means of the Internet (queries from remote PC units). 
- User friendly interface and minimal staff training 
requirements, mainly based on self-learning techniques. 
- . Usability on widespread average speed H/W machines 
with low-cost easy-maintenance O.S. 
-  Widely used interchange data format (of both 
alphanumerical and graphical data), which allows large 
portability on systems operating with different S/W.

CONCLUSIONS 
The use of computer technology is fundamental with the 
advantage that information in a GIS can be updated and 
modified very quickly in comparison with the traditional 
cartography. In this contest we can understand as the 
traditional 2D maps are often restrictive and overcome by 
more complete products, very descriptive, witch permit a 
three-dimensional and realistic representation. Today GIS, 
managed and completed by modelling instruments, is going 
to open a new age of Decision Support System in every 
contest as the environmental analysis mentioned. Real-time 
representations, DSS and dynamism are only components of 
the actual GIS application.
