Furthermore this company contracts for private and government institutes abroad for
air-photography and map-production. It has at Delft a mapping section which produces
large and small-scale maps and photomosaics commissioned by inland and by foreign
institutes and services.
The Cadastral Service instituted in 1955 a special photogrammetric branch, which
started production in 1957 after it obtained a stereoplanigraph C 8. Its activities are partly
the resurvey of areas in need of new cadastral maps and furthermore the production of
maps on behalf of the reallotment service. In the 1956 report it was stated that the Nether-
lands Government was considering how this new photogrammetric service could cooperate
with the existing organizations, so as to insure the maximum benefit of all experience gained
in the past and of all equipment available in the country. Unfortunately, this consideration
is still under discussion.
The activities of the educational institutes mentioned above have continued along the
same lines. In cHAPTER VI of this report, a few details will be mentioned. It is worthwile
to mention here that in 1956 an important geographical concentration of productive and
scientific institutes dealing with photogrammetry took place. At the end of 1956 the new
buildings established for the I.'T.C., for Meetkundige Dienst van de Rijkswaterstaat and
for the mapping section of K.L.M. Aerocarto were inaugurated. Since they are built
adjacent to the old Geodetic Institute of the Technological University (See fig. 1), the
latter being modernized in 1957, a close cooperation between all these services and insti-
tutes became possible. Since furthermore also the Military Topographic Service of the
Netherlands is in Delft, not far from the concentration of photogrammetric institutes,
mentioned above, it is easy for this service to contribute also to the common efforts for the
development of Netherlands photogrammetry.
Cooperation between all these services working as close neighbours can also be demon-
strated by means of personal relations. Professor Roelofs is also the scientific advisor of
