GIS Is therefore used in many different institutions, 
institutes and working organisations either private or state. 
All these applications of GIS have spatial data as mutual 
characteristic, and working organisations frequently use 
the same type of data. Since gathering and maintenance 
of data requires highly professional staff and high 
expenses, the only purposeful exit from such a situation is 
that all such organisations should share the data and 
expenses and to have an access to all databases 
(Stefanovic et al., 1998).

At the time of the most intensive construction activities, 
and especially after the homeland war, very significant 
changes have occurred at the territories of county 
districts, municipalities and cities. The destruction of 
objects, infrastructure, the change of population 
structures, devastation of natural and economic 
resourses, neglecting of single partsand the problem of 
mineral resources ask for complete reconstruction and the 
establishemnt of new photogrammetric and cartographic 
material (Biljecki and Tonkovic, 1999). The reseach of 
map graphics on digital photomap has been one of the 
activities that Franges and Posloncec-Petric (1998) have 
dealt with, and the photomap of the City Velika Gorica at 
the scale of approximately 1:6000 has been made by the 
authors S. Franges and Z. Biljecki for the ordering party 
“Administrative Department for Spatial Planning and 
Environmental Protection of the City Authorities of Velika 
Gorica” and have been acknowledged for the excellence 
in cartography at the International Cartographic Exhibition 
held in Ottawa in 1999. 
Geoinformation technology can use various sources, but 
the state level and the internal relation, as well as the 
European and world integrations request arranged 
system, and these are state official cartography and land 
register. It is therefore important to know the relations in
