In memory of DVW President Prof. Dr. Ing. Karl-Friedrich Thöne

Since the »Declaration of Bremen« (»Bremer Erklärung«) from 2008 the geo societies DVW (German Society for Geodesy, Geoinformation and Land Management) and DHyG (German Hydrographic Society) are friendly connected. On 15 July 2016 the President of the DVW Prof. Dr. Ing. Karl-Friedrich Thöne died unexpectedly at the age of 59 years. At a deeply moving sea burial off the island of Föhr we said farewell.
