The technical-scientific program of the Symposium will cer- 
tainly be interesting, but tiring. Therefore we have planned 
some social events for relaxing, and, thus, recharging our 
receiving capacity. In this connection I want to express my 
happiness that there are over 20 registered accompanying 
persons. In addition to the general social program, we have 
prepared for them a program of their own. 
This Symposium is dedicated to the memory of Dr.h.c. K.G. LOf- 
strom who passed away in 1984. Dr. Lôfstrôm was a pioneer in 
photogrammetry in Finland and participated also actively in 
the international affairs of photogrammetry. Dr. LOófstróm 
was Honorary Member of the Finnish Society of Photogrammetry 
as well as of the ISPRS. After this Opening Session the first 
Memorial Lecture will be given by Prof. Dr. F. Ackermann. 
Ladies and Gentlemen - I cordially welcome you all to the 
Symposium of Commission III of the ISPRS and I hope you will 
find it a rewarding experience. Further, I hope that you are 
enjoying your visit to the City of Rovaniemi end that the 
Lapponian circumstances will help create a good atmosphere 
for meeting your old friends and for finding new ones. 
I declare the Symposium open. 
Thank you.
