produced by digital photogrammetric mapping of areal 
photographs. Spots hights, structural forms, as break lines 
and formlines, also the mass points were considered. It 
resulted with the digital elevation model of high quality. 
The special condition for the Bay of Bakar is the existence 
of abandoned vineyards in the form of terrace, which are 
some kind of monument of human work and they are 
under the protection. Visualization of that area without 
digital elevation model of good quality is not possible, also 
as well as digital ortophoto production, too. 
With the purpose to show which are advantages of modern 
technologies, digital ortophoto for the area is produced. It 
represents good basis for urban planning, and as an visual 
information for protection of monument which is one of the 
main tasks in the next period. Implemented into the GIS as 
Bibliography: 
one of the layers, digital ortophoto gives to GIS better 
effectiveness. 
3.6.Conclution 
In projecting the environmental GIS it is of the most 
importance to respect all special conditions and 
characteristics of the area of interest. For the Bay of Bakar 
the most important is conflict of traditional i modern 
conditions. So, in this case, efficient GIS has to give a 
basis for the solution that should consider rich cultural, 
architectural and historic heritage, with industrial 
technologies implemented in the area, in order to protect 
the area.
