The first field campaign of the winter 2017-2018 was completed on 23-24th November 2017, with the participation of all the three partners. During the surveys on the rivers Mareit/Mareta and Ahr/Aurino, we collected topographic data, water velocity, water depth and substrate data and information about the mesohabitats. Simultaneously a detailed airborne mapping was performed, using UAVs, to collect RGB and hypersprectal imagery.
