phenomena have many possible consequences and that they have not thus far
been given all the attention they deserve.
Dr. Howlett: There is an opportunity now for the presentation of any
resolutions from the floor of the Commission.
Mr. Corten: There are several matters of navigation for aerial survey,
electronic navigation, visual or contact navigation, instrument navigation, and
only a few of these have been treated very briefly during this Congress. I pro
pose a motion that one of the future activities of Commission I should be
stimulating a mutual comparison of navigation methods, in a non-military
field of course, with special regard to the efficiency of these methods in flying
for aerial surveying.
Dr. Howlett: The general gist of this resolution would recommend that
Commission I in future pay more attention to navigational methods than it has
in the past. It seems to be a very wise resolution. Are there any further com
ments? If not, I will ask you to vote on the resolution.
The resolution was carried unanimously.
Dr. Howlett: We have prepared a draft of the report which will be
presented by Commission I to the Plenary Session this afternoon. I will ask the
Secretary to read this draft in order that the Commission may hear it and alter
it in any manner they see fit.
Mr. Carman: “The principal work of Commission I since the last Con
gress has been the preparation of an international specification which provides
a test procedure to permit the results of camera tests in different countries to
be compared. The preparation of this specification has been greatly assisted and
indeed made possible by much discussion with interested persons throughout
the world.
“Although an ideal solution to the requirement for a specification has by
no means been reached the Commission can report some measure of success by
the adoption of the present specification for trial, study, and discussion. The
Commission regrads this as a useful pragmatic solution for the difficult situa
tion but at the same time wishes to encourage research in this field so that the
specification may ultimately be developed to a thoroughly satisfactory level.
“In the interest of securing wide agreement, and completing a specification
in the time available, it was necessary to leave out of the specification certain
matters of interest. It is suggested that Commission I give attention to the
possibility of expanding the scope of the specification. Items suggested for
attention are definitions and translation of technical terms, a complete agree
ment on T-stops, a shutter test method, and a method of testing camera
mountings. In the course of discussing definitions it has appeared to be desir
able that the International Society of Photogrammetry should not independ
ently define terms which may be the responsibility of one of the International
Scientific Unions. For example, many terms should obviously be in agreement
with those which are or may be defined by the International Commission on
