Remote Sensing, The Canadian Institute of Surveying and other agencies. The fourth in this conti- 
nuing series will be held at Quebec City, Quebec, May 16-18, 1977. Proceedings of past symposia 
have been published and are available. The International Society of Photogrammetry, Commission VII - 
Photo Interpretation and Remote Sensing, conducted a sumposium on Remote Sensing and Photo Interpre- 
tation at Banff, Alberta, 1974. It was hosted by the Canadian Institute of Surveying and national 
sponsored by: The Government of Canada, Canadian Forestry Service and the Canada Centre for Remote 
Sensing; The Government of Alberta, Alberta Remote Sensing Centre; and the University of Alberta, 
Department of Extension. The chairman was Dr. L. Sayn-Wittgenstein, President of Commission VII. 
The symposium was an outstanding success, bringing together, in one of the world's most beautiful 
areas, some 200 leading scientists from 23 countries. The technical Program concentrated on the 
application of photo interpretation and remote sensing to resource inventories and environmental 
studies. The working groups and project teams of Commission VII were the foci for exchanges on 
these and related topics. 
The Canadian Institute of Surveying has for years stressed the importance of, and supported develop- 
ments in, photo interpretation by publishing in this field and regular technical sessions at its 
annual meetings. The Committee on Photo Interpretation and Remote Sensing is an important part of 
the Institute. At the international level the Canadian Institute of Surveying is the official link 
with the International Society of Photogrammetry. These ties are evidenced by the present President 
of the Canadian Institute of Surveying, Dr. L. Sayn-Wittgenstein also president of the International 
Society of Photogrammetry's Commission VII: Photo Interpretation and Remote Sensing. 
Remote sensing education is also carried out in the form of courses, such as the Alberta Remote 
Sensing Center's annual training courses. The fifth will be held in Edmonton in February, 1977. 
Educational institutions are providing disciplinary oriented remote sensing courses and incorporating 
remote sensing in various course curricula. The recent advent of opportunities for persons to 
acquire a working knowledge of remote sensing through symposia, meetings, technical papers and 
educational courses has increased the practical benefits to users of remote sensing. 
The immediate future will see greater use being made in Canada of all phases of photo interpretation 
and remote sensing as its practical benefits to users is developed. Automated techniques, computer 
and electronic equipment will allow the extraction of information from the wealth of data, in photo- 
graphic and non-photographic format, available for the survey and managment of the environment.
