mais des progrés trés considérables. Je me limite à vous citer quelques uns des arguments qui sont, à mon avis, 
les plus importants. 
l. Les "remote sensing", dont l'étude du point de vue photogrammétrique à été commencée à Lausanne, 
occuperont d'une facon approfondie les Commissions I et IV et VII. 
2. L'automation en photogrammétrie qui a bien progressé dans certains pays est, certainement, un des 
thémes les plus séduisants de discussion, par suite de ses énormes possibilités et à cause des difficultés 
considérables qu'elle présente. 
3. La triangulation aérienne a fait de grands progrés en ce qui concerne sa précision et son application à 
des grands blocs et aux grandes échelles. 
4. L'économie des projets de levers photogrammétriques est attentivement étudiée par la Commission 
IV. 
s. Les applicátions non topographiques de la photogrammétrie augmentent chaque jour en étendue et en 
importance. 
6. La photointerprétation a atteint une dimension nouvelle gráce à l'emploie de satellites artificiels qui 
permettront aussi de dresser, dans un proche avenir, des cartes à petite et peut-étre à moyenne 
échelle. 
7. Finallement, je tiens à vous rappeler le projet d'une **Histoire de la Photogrammétrie", que le Général 
Lófstróm présentera à la Commission VI. Il s'agit d'une oeuvre trés importante, à laquelle tous les Pays 
Membres sont appelés à collaborer. 
Vous pouvez donc constater, que le matériel de travail et de discussion ne manquera pas au cours des 
séances des Commissions Techniques. Les Présidents de Commissions, que je remercie pour ce qu'ils ont fait 
jusqu'ici, et pour ce qu'il feront pendant les prochains jours, auront de la peine à contenir les discussions dans 
les limites imposées par le temps disponible. 
A vous tous, j'addresse mes meilleurs voeux de bon travail et de séjour agréable à Ottawa. 
Dr. Gamble: Thank you Mr. Speaker. Our keynote speaker is well known to most photogrammetrists, certainly 
in North America and I believe well beyond the seas. He has contributed to the advancement of photogramme- 
try in many ways as a teacher, research scientist and almost equally more important as an Ambassador of 
Goodwill. When it became my responsibility to select a keynote speaker for this Congress, I knew who I 
wanted, my difficulty was to try to persuade him to undertake the task knowing his busy schedule. I won't spend 
too much time enunciating his long and distinguished career but just mention a few things. He is presently a 
research scientist for Mapping Systems at the U.S. Geological Survey; Chairman, Apollo Orbital Science 
Photographic Team, responsible for the planning, development, operation and data reduction of camera 
systems in Apollo Lunar Programmes. Awarded the NASA medal for experimental scientific achievement for 
this work. Formerly Chairman of Geodesy and Cartography Panel of National Academy of Science - a study 
of peaceful applications of space - deliberations of that study won him a medal in deciding the need for and 
design of earth resources technology satellite which we heard about today. He is also a past President of the 
American Society of Phtogrammetry. Ladies and Gentlemen, it is with great pleasure that I call upon Mr. 
Frederick J. Doyle for our keynote address. 
PHOTOGRAMMETRY AND THE FUTURE 
Frederick J. Doyle 
U.S. Geological Survey 
President Solaini, Chairman Gamble, distinguished guests, ladies and gentlemen. When Mr. Gamble 
first asked me to give this talk, I held off giving him an answer. As the man said when he was being ridden . 
out of town on a rail, “If it weren’t for the honour, I'd just as soon not go’. Nevertheless, once having accepted | 
the task, I will admit that the opportunity of pontificating before my peers developed a certain powerful 
attraction. In the intervening months I have thought seriously about what I might say to you, for to waste a 
half hour of the time of so large and prestigious a group ought to be a hanging offence. I would like to share 
with you some thoughts on ‘Photogrammetry and the Future”. 
Four years ago many of us attended the XIth Congress of this Society in Lausanne. We came away from 
there impressed by the hospitality of our Swiss hosts, by the efficiency with which they conducted the Congress 
affairs, and by the well-being of our profession. We had listened to a number of exceptional papers, seen an 
outstanding exhibit of photogrammetric instruments and products, and enjoyed stimulating personal 
exchanges with our colleagues from different countries. There was good reason to believe that all was well in 
the world of photogrammetry.
