We are glad to announce that our search for a new colleague was successful. Starting on March 01, 2010 Mr. Christian Mayer will complement our team initially on 2.5 days per week since he still has a contract with the University of Bonn until June 30, 2010. After this date he will work full-time for terrestris. Christian Mayer studied geodesy and geoinformatics at the University of Mainz in the working group of Prof. Alexander Zipf. terrestris extends a warm welcome to Christian and looks forward to the collaboration!
