OPENING REMARKS L. Sayn-Wittgenstein President, Commission VII This will be a brief report to introduce this Symposium and to comment on the current programs of Commission VII. You will remember that the Earth Resources Technology Satellite was launched during the Ottawa Congress two years ago and the interpretation of ERTS imagery has dominated most other interpretation problems since. We are now returning to normal, after passing through a period of excessive enthusiasm, through a lull during which experiments were being completed, into the present period when results have begun to exceed the most optimistic expectations - at least for those who have access to advanced interpretation systems. You will hear some of these results during this Symposium. But these new achievements have also posed new problems and things will never be the same again. The many experiments involving interpretation of digital data have brought it home to us what a quantitative discipline interpretation has become. Exact mathematical definitions and statistical approaches to pattern recognition are rapidly becoming standard interpretation procedures. The critical limitations in the use of aerial photography and remote sensing imagery are no longer resolving power and other measures of image quality, but the methods for extracting useful information from the mass of data available to everyone. By involving automation, computers and electronics in the solution of this problem, Commission VII is dealing with methods and objectives that are central issues in the International Society for Photogrammetry. Several immediate priorities are well expressed by the array of working groups of Commission VII. To these we can add other tasks which clearly deserve more attention. There is, for example, the need to establish that conventional interpretation and the new technologies of remote sensing are not competing systems, but rather complementary methods that must be combined to meet whatever demands we choose to make from them. Also we have not made as much progress as there should have been in the interpretation of side-looking radar imagery, and in studies of imagery from high resolution weather satellites. How should Commission VII meet its objective? To put it more speci fically, what program would you like to see at Helsinki in 1976? The present Symposium, and several other recent symposia have emphasized ''applications". Have we ignored the importance of basic research and interpretation concepts by responding to pressures for proof of useful applications and big benefits? I hope that the discussions and resolutions of this Symposium will attack this problem. You will notice that the Symposium program deviates somewhat from the structure of Commission VII working groups. One reason ds that the Symposium theme is "Applications" which does not cover all aspects of
