situation and to draw the attention to some implications and consequences which are the results 
of the actual development. The technical development in general is dramatic. Equally violent 
is the improvement of the technical performance in photogrammetry and remote sensing. On 
the other hand are also the induced changes most thorough, concerning products, user groups, 
professional substance and professional organisations. The new levels of technology and the. 
effects of automation in general launch tendencies of integration with other disciplines which 
in turn open up new competition. 
There is no reason to be pessimistic in view of the imminent changes. It is an inherent feature of 
evolution and development that old structures disappear, and that new structures are composed. 
Some flexibility is certainly required. But the realization of and the reaction to the development 
constitutes a major challenge. To meet it is in fact a fascinating task which will result in new 
structures. 
I am convinced that the professional societies of photogrammetry and remote sensing and the 
professionals in tins field are able to meet the challenge, in connection with and by combined 
efforts of the neighbour disciplines. This symposium will look particularly into the implications 
and the problems concerning education. I wish the best of success, as far as the immediate 
problems are concerned, but also with regard to the long range aspects of our profession.
