5. PRODUCTION OF DIGITAL ORTHOPHOTO MAPS 
In the period of intensive construction from 1980 to 1990, 
especially during and after recent war, regions of Croatia 
have been significantly changed. Building and infrastructure 
destructions, changes of inhabitants structure, destruction of 
natural and economical resources, no development and mine 
pollution problem of different regions require integrated 
updating and production of new data bases (in digital form) 
for creation of geoinformation system. 
Considering the needs and the costs of topographic maps 
production, as well as time needed for their production, State 
Geodetic Administration came to a conclusion that digital 
orthophoto maps could give enough satisfactory solution for 
wide field of extant problems. 
The first contract was signed in the year 1994 (Jastrebarsko i 
Gorica) and the first 18 sheets were finished in 1995. Till 
2001 digital orthophoto maps were produced as supplement 
product to the Croatian Basic Map at the scale 1:5000. 
In July 2001 the Program of the State Survey and Real Estate 
Cadastre for the period from 2001 till 2005 was delivered and 
published in Official Gazette N.N. No. 64/2001. Trough the 
program establishment of multipurpose spatial information 
system for the purpose of space management carried out by 
state authorities and public enterprises (Subprogram C) is 
foreseen and encompasses production of 5000 sheets of digi- 
tal orthophoto maps 1:5000 (DOP) which corresponds to the 
half of the Croatian territory. A new strategy was accepted. 
Since that time production of orthophoto maps at the scale 
1:5000 has been made from the cyclical photogrammetric 
survey records independently to the Croatian Basic Map pro- 
duction and according to the interests of State Geodetic Ad- 
ministration and other coinvestors. 
Namely, State Geodetic Administration is responsible for 
production of all official cartographic and geodetic bases for 
civil purposes in the state, but there are also local authorities 
as well as some public institutions interested in their produc- 
tion. Considering that fact in the most cases of digital ortho- 
photo maps production State Geodetic Administration con- 
cludes an agreement about its production with mentioned 
parties. According to such agreements State Geodetic 
Administration becomes owner of digital orthophoto maps 
and other parties get usage right.
