2.1 Chronology 
2001 1s a year of a significant change. This is initiated by the 
decision of the Belgrade city management to finance DOP 
production for approximately 1.000km? of the Belgrade 
territory with pixel size of 30cm. The objective was to use DOP 
as a basis for making master map of the Belgrade. This project 
was finished for 90 days form the day when aerial photography 
was made. The success of further activities related to master 
map was greatly depending on the strict adherence to required 
‘DOP quality and project time schedule. Fortunately, the 
Belgrade master map was at the centre of public attention at that 
time, so the publicity was in the chance to directly discover the 
effects of DOP application in the area of town planning. Due to 
that, already next year (2002) DOP projects of following cities 
and municipalities started up (Table 2): Lazarevac, Lajkovac, 
Loznica, Pozarevac, Pancevo and Kragujevac. This trend 
continued in the year 2003 when DOP for the whole territory of 
Belgrade was made up, as well as the territory of Smederevo 
and Vrnjacka Banja municipality. All of these projects have 
very similar technical characteristic (photo scale 1:14500- 
1:20000, resolution 0.3mx0.3m, grayscale or color). 
The proof that these projects are not just accidents is proved by 
the fact that interest in DOP remained in the year 2004, where 
several big DOP projects wait to be carried out (for instance, 
Valjevo, Novi Pazar and Sabac). The interest of some other 
municipalities is also important and tremendous (Figure 1, 
Table 4). If this trend remains in the next several years, Serbia 
will be 100 % covered by DOP in adequate resolution.

2.2 Digital orthophoto production process 
Prevailing DOP production process in Serbia is still based on 
standard aerial photogrammetry procedure. All projects 
(showed in Figure 1 and Tables 2, 4) are realized or will be 
realized in the same way.

Figure 3: Standard procedure of DOP production based on 
aerial photogrammetry 
Standard production procedure assumes simple production line 
shown at Figure 3, which starts with image capturing and ends 
with mosaicking of DOP. GCPs are provided after image 
capturing using striking artificial object, clearly visible both on 
images and the ground. All points are of the same rank, 
distributed in raster (interval cca 2 stereo basis). Digital terrain
