We are very greatful that the industry has ac 
cepted our invitation to exhibit their most recent 
instruments during this Symposium. 
I expect, that during this week’s discussions we 
will have to face the need for compromise between 
precision and productivity, for instance in the 
manufacturing of townmaps in developing countries 
and in the acquisition and monitoring of environmen 
tal data. In this respect it is a great comfort that 
Professor Konecny and Dr. Tbrlegard honour us with 
their presence, as well as other ISPRS members who 
are familiar with the work that is going on in the 
other six ISPRS Commissions. 
The key-note address of Professor Konecny today will 
provide a reference, essential to our further dis 
cussions. 
Finally, I should like to challenge you all to 
direct your discussions primarily towards techniques 
and applications of remote sensing which can con 
tribute to operational solutions in the foreseeable 
future for some of the development problems I have 
mentioned. We shall review the results of your 
discussions during our closing session. 
Ladies and Gentlemen, 
As I told you, I am grateful for your presence, I 
am also grateful in advance for your contributions 
in presentations and in the discussions. 
I wish you all a very enjoyable week. 
Thank you for your attention.
