Distinguished guests, dear Colleagues 
Ladies and Gentlemen 
As president of Commission V! of the ISPRS and on behalf of the Organizing 
Committee I have the privilege to welcome you all to our Med Congress Symposium of 
1990. 
When we started the preparations for this Symposium I thought that the moment 
of addressing a welcome to you would be the most relieving and relaxing. Now I know 
that! have to wait until the symposium is over, and then I hope I will be in a position to 
say that it was very good but I am glad that it is over. 
The board of Commission VI, the Greek Society of Photogram metry and Remote 
Sensing, the National Technical University of Athens and especially the Department of 
Topog'aphical Engineering, the Technical Chamber of Greece, the Hellenic Cadastral 
and Mapping Organization, the Hellenic Association of Surveying Engineers and the 
Organizing and Scientific Committees have all tried to make the symposium as official 
and productive as possible. 
To make it official we have made a lot of effort and it was necessary to 
overcome many difficulties to hold this opening session in the famous and beautiful 
Castelio of Rhodes. The Castello was used to house the first summit meeting of the 
Heads of Government of the European Economic Community in December 1987, 
when Greece held the presidency of the EEC. To get the Castello for Commission VI 
was not an easy task. We have to thank Mr Kolias, head of the Archeological Service 
in Rhodes, and his collaborators, the Mayor of Rhodes and the author ities of the City 
who supported the idea, the Director of the Archeological Service Prof. Zias. the 
Central Archeological Council in Athens, the Secretary General of the Ministry of 
Culture and last but not least the Minister of Culture Mr. Tzanetakis who supported and 
approved of the idea.
