On the Day of Teaching at U Potsdam I will give a talk about the MATLAB/LEGO MINDSTORMS practical, sponsored by MathWorks Inc. The practical, part of the master’s courses “Geosciences” and “Remote Sensing, geoInformation and Visualization“, as well as of the Summer School on Earth Surface Dynamics, aims to improve student’s skills to build efficient teams to solve typical problems in earth sciences in acquiring, processing and analyzing typical multispectral (visible, infrared, thermal), geophysical (seismic, magnetic) and geometric (2D, 3D) data.
