Plastic detection from satellites in oceans worldwide
Lobelia Earth uses Synthetic Aperture Radar (SAR) images for the identification of plastic signatures in marine environments. Space-borne radar technology ocean remote sensing has indisputable benefits since it provides an all-weather, all-day (independent of sunlight), wide-swath monitoring of the sea.
We combine different types of information gathered by the radar sensor and use algorithms to enhance the detection of marine debris in combination with meteorological information, employing a pattern recognition approach based on computational intelligence techniques. This enables the generation of a data-driven model trained and validated for the study area, the Balearic Islands, and the testing of model generalisation with other reported plastic pollution events in different scenarios and geographical locations.
