West Germany normal angle (f = 210 mm) camera as well as the 
plate camera RC 7a were used, Some test flights were made with 
VEB Carl Zeiss Jena and Wild RC 10 wide-angle cameras. 
Ihe annual output has been a mean 12 000 black-and-white and 
1 000 color aerial photographs per year, From these films about 
60 000 black-and-white and 2000 color copies were yearly made, 
Aerotriangulation 
Ihe analytical method of adjustment with bundles of rays is not 
only a new method under examination, but is already in daily 
practical use, The Finns are also serving results from this 
type of aerotriangulation by order of other European countries. 
For the measurement of image coordinates in a comparator there 
are two Zeiss West Germany comparators PSK, one at Helsinki Uni- 
versity of Technology and the other one at the National Board 
of Survey, 
In addition there are two older Stereoplanigraphs at the Natio- 
nal Board of Survey which are in use as analog triangulation 
instruments for less accurate purposes and one Wild A7 by the 
private enterprise Kaavakartta Oy. Other pri- 
vate enterprises use Wild A8 instruments occasionally also for 
analog triangulation, Early in 1972 the Institute of Photogram- 
metry got a Finnish made digital registration equipment for an 
older Stereoplanigraph C5 for non-topographic analytical photo- 
grammetry. 
Especially interesting are some practical studies by the Insti- 
tute of Photogrammetry in which coordinates of new fixed and sig- 
nalized points were determined for later geodetic and cadastral 
purposes, 
The annual output in our country has been about 1800 analytical 
measured models a year.
