member, paying a lack of content unfortunately frequent in the university people; indeed WG VI/3 according to its 
Terms of Reference cannot neglect or dismiss contributions from industry, engineering firms, etc. 
Consequently TC VI and, particularly WG VI/3, could play an important role with the aim to enlarge the participation 
and to have activities at a really important level. Indeed the bigger danger is to restrict the responsibility and 
participation to a few number of countries and/or groups. There are two possibilities to overcome these troubles: the 
foundation of democracy for an elite or to enlarge democracy and participation. The Working Group has chosen the 
second hypothesis. Its spirit, promoting the contributions of young people and people coming from developing countries 
and reaching 355 members between participants and correspondent members, involving 57 countries (more than 50% of 
the ISPRS Ordinary Members), proofs that WG VI/3 is going in the correct direction. 
The volume of the proceedings collects the contributions of the technical sessions, poster session and tutorials, as well 
as the compte rendu of the meetings and the list of participants and correspondent members.
