than hundred people, the learning curve has been particularly steep for us. As a result, mistakes were unavoidable and 
we would like to apologise with the authors and reviewers for any inconvenience that they may have experienced. We are 
confident that together we will be able to solve this challenge for future scientific meetings to the benefit of our discipline. 
Finally, we want to highlight the very positive fact that we have received many excellent papers from scientists from 
developing regions. This suggests to us that ISPRS has been quite successful in stimulating the exchange of scientists 
from around the world and diverse cultural background. This will become the ever more important as climate change, 
continued population growth and shrinking natural resources have all become truly global problems that require, as one 
small part of the solution, global observation capabilities to better understand of how we have to act locally.
