In this course, participants will get an introduction to cloud-based image analysis techniques for monitoring surface water dynamics with use of EO data. It will cover general concepts of radar and optical remote sensing, how those instruments interact with water surface and which infor-mation they can provide. The key datasets to be used include Copernicus Missions: Sentinel-1 and Sentinel-2 for water bodies monitoring and hazards. For practical exercises participants will use Jupyter Notebooks and image processing software available on the cloud computing platform.
