The studies and special applications have retained their character of isolated 
research — rather than regular and generalised application — during the four 
years since the Washington Congress. 
Although the non-topographical applications of photogrammetry are already 
very numerous and very important, the small number of specialists and in 
struments and the difficulties in making the uninitiated understand the 
advantages that can be gained from photogrammetry are still the main reasons 
for the limited use of these methods in all countries, even the most highly 
developed ones. 
We must nevertheless note the prediction of Mr McNeil, who believes that 
the non-topographical applications of photogrammetry will outclass the carto 
graphical applications in a near future. 
2. No new method of fundamental importance is to be observed in the papers 
received. Some new instruments for photography and for special purposes have 
been devised, but there is nothing new in the field of special plotting instruments: 
nor is there yet any detailed systematic classification of the special applications 
of photogrammetry: during the next four years such a classification of the 
applications already in existence should be considered. 
3. Research and experiments in the very extensive field of special applications 
should be encouraged as much as possible: the topographical applications have 
undoubtedly absorbed most of our efforts up to now: but today we can say 
that topographical photogrammetry is so well developed that it no longer 
demands the collaboration of all photogrammetrists. Therefore, in the future, 
more time, more study and more experimental work can be devoted to the 
methods and apparatus intended for non-topographical photogrammetry. We 
request the National Societies to invite their members to direct part of their 
efforts in this direction. We recommend that a synthesis of existing literature 
and literature to be published in the near future be made and we propose that 
an international competition be held for a non-topographic photogrammetric 
treatise which should be both theoretical and practical, giving as clearly and 
completely as possible an account of the present knowledge in this field. 
4. It is desired that instruction in non-topographic photogrammetry be 
introduced in institutions of higher education, in those subjects where its 
applications can contribute to scientific and technical progress (geology, soil 
science, civil engineering, medicine, meteorology, forestry, etc.). 
5. Research and experiments in the field of special applications should be 
granted the support of the National Societies and the specialised industries, 
especially with a view to the establishment of archives and photography of 
architectural masterpieces and in connection with studies of scientific or 
artistic interest such as radiographical photogrammetry, study of the infinitely 
large (astronomy) and the infinitely small (molecules) measurements of waves 
and clouds, glaciers, fluids in movement etc. 
6. It must be admitted that during the last four years the work done reveals 
a lack of coordination, even between the specialists of the same country. Often 
they do not even take into account knowledge already gained. 
It would therefore be desirable to create in each National Society a special 
section in which all those interested in these questions could come together. 
Periodical contacts would allow the possibilities and advantages of photo 
grammetry to become better known. 
It may be concluded that the non-topographical applications of photo 
grammetry are making constant progress, and it is certain that they will spread 
and assert themselves more and more in the future. 
The proposal was adopted without discussion.
