The Marine Remote Sensing Group (MRSG) in the University of the Aegean conducts research for the exploration, analysis and visualization of the satellite and UAV data in the coastal environment. We combine state of the art algorithms and in situ measurements to develop new methods, technologies, and products for the visual representation of marine geospatial information. The group has gain expertise in several disciplines of marine remote sensing including oil spill detection, oceanic phenomena identification, seagrass mapping, coastal bathymetry and coastline detection. Hereafter we present ongoing and completed research projects.
