Photographic missions according to the general plan for
the official mapping are carried out using black and
white photographic materials. In photography carried out
on a repayment basis, however, colour and infra-red
colour film are used to a considerable extent In the
last few years about 40 % of the negatives, corresponding
to some 6 000 frames per year,were exposed on different
colour materials.
A very large number of contact prints, diapositives,
enlarged photographs and rectified photographs are supplied
from the photo library of LMV, which now contains some
700 000 aerial photo negatives.
In tables 1 and 2, production results for the period
1972-1975 are given.
