non-topographic photogrammetry, one by Mr. A. J. v. d. Weele: "Wave measure- 
ments by means of Photogrammetry" and one by Mr. H. C. Zorn: "Applications 
of non-topographic photogrammetry in the Geodetic-Institute". 
CHAPTER VI. 
Regarding Comm. VI dealing with education, terminology, bibliography, 
history and polyglot dictionary, we must admit that the problem of bibliography oí 
photogrammetry has still not found its international solution. The author took the 
initiative to start a bibliography in the Delft I.T.C. for its own use. Experience, 
however, showed that without some international cooperation, it will be impossible 
to publish a bibliography which can be used all over the world. Recently we 
learned that in various institutes parts of such a bibliography were being made and 
we hope that the Stockholm Congress will provide a possibility to reach a solution 
for this problem of international cooperation. The Delft ITC is willing to undertake 
the publication and distribution of such a bibliography if such cooperation can be 
organized with some national societies of photogrammetry or scientific institutes. 
We feel it to be unsatisfactory if a bibliography appears only at each congress, 
that means with an interval of four years, as in the past. 
Regarding terminology | draw attention to the effort made by the author 
to propose a certain standardisation of signs in the general formulae used in photo- 
grammetry (12). The publication by Dr. Jerie (14) in the same issue of Photo- 
grammetria shows the chaos in this respect, which makes the understanding of 
formulas in publications in different photogrammetric reviews very difficult. We will 
therefore, at the International Congress in Stockholm, come with a new proposal 
based on suggestions which I received after the article of 1955. We hope that in 
particular also the industry will take into account the decisions — if any — accepted 
by the Congress. 
As regards education no important changes as compared with the 1952 Report 
can be mentioned. Education at the universities for Technology (Delft) and Agri- 
culture (Wageningen) continues in the same way. Important, however, is the 
establishment of a new large building for the Delft I.T.C. in close connection with 
the old Geodetic Institute of the Delft University of Technology. In this new building 
are also housed the photogrammetric section of the Geodetic Institute and the 
collection of photogrammetric instruments of both the Geodetic Institute and the 
Delft I.T.C.; they are treated as one unit for common use. When designing this 
building all kinds of provisions were made, in particular in the rooms for first-order 
instruments, in order to avoid known and unknown sources of errors. Therefore 
the floor of this room is a big concrete sheet of 35 cm on 40 rubber cushions of 
30 cm diameter and 30 cm hight and naturally the whole room is airconditioned 
with tolerances of 2 degrees for temperature and 5 % for humidity. Four floors 
of this building of 8 stories, excluding a basement for laboratories, are occupied 
by the 50 rooms for foreign students of the I.T.C.
