Aerial hydrographic surveying
As part of the Comet-K project, two workshops were held at which users and project partners reported on their experiences and findings and were able to exchange views with one another in expert panels. A total of 150 participants from various scientific and industrial sectors attended the events to learn about the current status and potential of airborne hydrographic surveying.
The links below provide further information on the events and allow you to download the presentations from the individual talks as PDF files.
1st Workshop on the Comet-K Project “Alpine Airborne Hydromapping”
This took place on 23 February 2015 in Innsbruck. You can download the presentations via the links below.
