sensing, photo interpretation, airborne methods such as aeromagnetic exploration) there are approximately 170 
people with a university degree, 330 technologists and technicians and 1,000 auxiliaries (plotter operators, photo- 
graphers, etc.) according to a distribution ratio of approximately 1:2:6. Accepting a 20-year renewal period the 
number of annually graduating professional photogrammetrists at the university level and at the present time 
would be approximately 10, for professional photogrammetry technologists and technicians 20, and on the auxiliary 
level an annual out-put of 50 trained personnel would be provided. These figures must be considered as very 
preliminary and it will be necessary to carefully analyze in the near future photogrammetric manpower require- 
ments and to work out realistic projections. In particular it must be investigated whether the existing ratio of 
approximately 1:2:6 between the three educational levels is appropriate in order to achieve optimum proficiency 
and quality of photogrammetric operations. 
The ‘photogrammetry equipment available at various educational institutions depends on the degree of con- 
centration on photogrammetric education, The photogrammetry programs at both Laval University and University 
of New Brunswick dispose of photogrammetric equipment worth about half a: million dollars each, 
In a similar way the number of photogrammetry courses at various institutions varies from 1 to 20, 
As far as new trends in photogrammetry education are concerned, particularly on the university level, it 
can be noticed that besides classical photogrammetry more emphasis is given on automation, electronics, com- 
puter. applications, remote sensing and photo interpretation, 
Terminology 
No particular activity can be reported as far as terminology is concerned, 
Bibliography 
Although there is no national coordinating body being responsible for setting up and keeping up-to-date a 
bibliography on the entire photogrammetric literature, there are various individual organizations which very 
probably have their own bibliographies on photogrammetric literature and computer programs, However, no 
comprehensive and recent survey has been made up to date regarding such bibliographies, This might be a task 
to be achieved during the period between the Ottawa Congress and the subsequent International Congress of 
Photogrammetry in 1976, 
COMMISSION VII 
Photo Interpretation and Remote Sensing 
Reporter: L. SAYN-WITTGENSTEIN, Forest Management Institute, Canadian Forestry Service, 
A National Remote Sensing Program 
Much has changed in remote sensing and aerial photo interpretation during the last four years, The main 
development has been the establishment of a national remote sensing program, coordinated by the Canada Centre 
for Remote Sensing under the auspices of the Ministry of Energy, Mines and Resources, The organization of the 
Centre provides for strong influence on policies and programs by other federal agencies, provincial governments, 
universities and the private sector. The Centre's activities are primarily concerned with airborne- and space- 
sensing readout and data processing. 
The establishment of the Centre, and decisions on its main programs and objectives were preceded by a 
comprehensive review of remote-sensing activities in Canada, This review was in part carried out by thirteen 
Working Groups. These Working Groups represented resource-oriented disciplines (e.g. agriculture, forestry) 
and the relevant fields of remote sensing, satellite and aircraft technology. The reports of these Working Groups, 
recently published by the Canada Centre for Remote Sensing, give a good picture of the state of the art, the 
objectives and problems in remote sensing in Canada, 
An immediate accomplishment of the Centre has been the provision of several aircraft for remote-sensing 
experiments, This has stimulated and strengthened the developing use of ultra-small-scale photography, of 
Scanners and other sensors, 
Another major program is connected with NASA's plan to launch a series of Earth Resources Technology 
Satellites (ERTS) beginning in 1972, Canada has entered into an agreement with the United States under which 
Canada would set up its own data readout and data-processing facilities. The readout station is to be in Prince 
Albert, Saskatchewan (Figure 1); the data-processing and distribution facilities will be at Ottawa, Several 
agencies have made plans for specific experiments to evaluate ERTS imagery and documentation of test areas 
has begun, 
The Canada Centre for Remote Sensing and the Canadian Institute for Surveying co-sponsored the "First 
Canadian Remote Sensing Symposium" held in Ottawa, February, 1972, Almost 500 persons attended and over 60 
technical papers were presented, The Proceedings, now in press, will provide a detailed summary of recent 
progress,
