22 
metric and photo-interpretation titles into an A- and B-series with photography and carto 
graphy in common. In this year until August another 800 titles will be published in this 
way. Most of the libraries (out of the 132 paying subscribers), however, prefer to receive 
the full bibliography. We expect, however, a number of new subscribers for the separate 
A- and B-series. 
The end of 1964 will bring the bibliography to a total of over 3,000 titles and with this 
we hope to be in a position to publish the abstracts of the well-known reviews within 
three months after their publication. 
Unfortunately the plans to publish also a bibliography of all patents as discussed in our 
1960-report have not been realized. It seems that this is too complicated for the national 
societies. The author of this article, who will be in the future in charge of the bibliography, 
has the intention to ask the cooperation of the industry for this. 
Furthermore the ITC Information No. 8 in which the UDC classification is published, 
as far as used in the bibliography, needs a second edition at the end of 1964 with correc 
tions and additional code numbers. 
Regarding education there was no considerable change since 1960 in the photogrammetric 
courses at the Agricultural and Technical Universities. There was, however, much greater 
interest among the students for geodetic engineering to take photogrammetry as the main 
subject for their final examination than in an earlier period. It is not unlikely that this is 
stimulated by the arrangement of the exercises with the ITC as mentioned in the previous 
report, which gives the student a closer contact with and a more favourable impression of 
photogrammetry. We mention here also the appointment of Prof, van der Weele at the 
Technical University to lecture for the geodetic students and in the near future also for 
the civil engineering students about the application of photogrammetry to engineering. 
Furthermore the Netherlands universities show an increase in courses for photo-inter 
pretation. Utrecht, who had a course in geological photo-interpretation for the geographers, 
has at present started a course in geographical interpretation. In Groningen a course has 
been started in social geographical photo-interpretation after the instructor followed a 
course at the ITC. The Delft mining engineers and the Amsterdam geologists have now a 
course in geological interpretation. Leiden university has a close cooperation with the 
geological branch of the ITC, having two staff members in common. In the Agricultural 
University, Wageningen, Prof. Buringh started a course in photo-interpretation for soils. 
For all these courses a further specialisation in the ITC is possible. 
The educational system of the ITC is extended with a new branch C, in which a regular 
course of instruction in aerial photography and survey navigation is organized. This course 
deals with the theoretical background and provides for practical instruction in image 
formation, survey navigation in flight and laboratory research. In this branch two special 
isations are possible: a) the production of aerial photographs and survey navigation, 
b) physics as applied to the production and to the performance of the photogrammetric 
image, leading to image systems engineering. Both courses are made up of approximately 
700 lecturing hours and 1,600 to 2,000 hours of practical work, depending on the trainee’s 
ability. The time necessary to complete either of them is for those who do not have already 
a good experience and preliminary theoretical education approx. 1 \ year. 
The ITC considers these courses as an important contribution to the improvement of 
practical photogrammetry which justifies the financial burden for its budget, due to the 
small number of trainees which can be accepted at the same time. 
The development of the participation at the ITC courses is shown by tables 6, 7, 8 
and. 9 taken from the annual report 1963.
