means of the ground control. The Jury would examine also the working con-
ditions, concerning the time elapsed, the difficulties encountered and the net
cost. I am sure that France will accept the execution of this test under condi-
tions which I guarantee will be entirely impartial”,
After a brief pause, General Hurault resumed the floor to add, “If the
manufacturers do not wish to rake part in such a competition, why not orga-
nize it with the collaboration of the National Geographic Institutes of official
services who would like to participate in it?
The President then requested to be informed of the opinions of the several
manufacturers most directly interested.
M. Gilliard (Belgium), former Director of the Military Geographical
Institute, explained that he spoke still as a user and not as a manufacturer. The
Belgian Military Geographic Institute had machines of three different trade
marks and could, consequently, compare them. Until now, out of circumspec-
tion, it had published no comparative results. It might be disposed to do this if
the manufacturers avoided the proposed competition.
At 2.02 Mr. Harry (Switzerland) declared himself in agreement with
General Hurault. It would be marvelous if a catalog could be obtained with
written observation on the machines. But France would undertake a great re-
sponsibility in organizing such a competition. In aviation, they have standards
fixed by the international organizations for measuring performances; could we
not go in the same way in the same direction, but in making only the first
step: classify the plotting machines by well defined standards both of preci-
sion and price. If you can do what you propose, do it, but I question what
you will arrive at. This is why I say, take only the first step, but I am not
opposed to the French proposal.
Mr. Poivilliers resumed the floor (2.08), "These competitions," he said,
"will permit of improving and making progress in methods, particularly
aerotriangulation”.
The President then put the French proposal to the vote. The proposal
was carried by 12 votes to 7, the other delegates present having abstained.
Mr. Poivilliers, then made another proposal tending to limit, during the
proceedings of the technical commissions of future Congresses, descriptions
of the general principles of apparatus, details being given at the booths of the
exhibitors.
Such a motion was already proposed by General Brown, and was adopted
«t the meeting for Presidents; it will be presented to the plenary session.
The session is adjourned at 2.15 p.m.
The definitive text of the French proposal was directed to the Council
of the International Society, as follows:
«Committec AL of. the International Congress of Photogrammetrv,
dealing of plotting methods and equipment, and of results obtainable, in its
session of 12th of September afternoon, expressed the following proposal, which
was adopted by the majority of votes:
"In order to promote among researchers and constructors an emulation
which would result in progress for Photogrammetry, Committee II proposes
that international photogrammetric competitions should be set up, in order
to study special problems, such as large-scale surveys, median-scale and small
scale surveys, bridging, aerotriangulation, etc.
