3. SURVEY OF THE INACCESSIBLE TERRAIN 
Topography of the terrain which is hard to access 
accessible is very specific and complex. The problem of 
surveying of such a terrain can be very successfully solved 
using non-contact methods such as photogrammetry. 
However, the standard photogrammetric method 
(photography using professional camera, measurements 
on analog stereoplotter) is very limited in such cases. The 
procedure presented in this paper (Joksié et al, 1994) has 
been based on photography using non-metric camera and 
data processing using the RolleiMetric MR2 
photogrammetric system. 
The test area typical for the for the design of structures on 
communications (bridges, tunnels, viaducts) was chosen. 
Th photos made by use of the non-metric camera and 
coordinates of five control points were the only field 
measurements. Data processing was carried out using the 
RolleiMetric photogrammetric system. Photo images were 
reproduced using ordinary photo paper with the 5 times 
enlargement.
