The difference in the number of study months between interpretation and photogram-
metry is not only due to the greater number of students for photogrammetry but also to
the fact that the photo-interpretation courses are on an average about half a year, though
with a larger attendance and for photogrammetry the average is close on a year.
TABLE 8 shows the number of students until the end of the 1959-1960 course.

One of the important aspects of study in the I. T.C. is not only the unique collection of
photogrammetric equipment, but in particular the close contact of the staff with problems
in aerial survey as they rise in all parts of the world. This is realized by the activity of
several staff-members for shorter or longer periods as experts for United Nations and for
foreign governments. This may be illustrated by the fact that during the last academic
year, 6 I. T.C. staff-members were serving on 3 continents outside Europe.
The second effort to remain in the closest possible contact with practical problems is the
newly established I.T.C. Consulting Department. Through this, the complete I. T.C. Staff
is made available to industry, private enterprise and government services, for all kinds of
consultation regarding the application of air photography to map production and for
economic interpretation.
