"VIIRS night-lights radiance (NASA Black Marble) over the eastern Po Valley, analysed with the astronomy Source Extractor tool (SExtractor / SEP) running in Galaxy (usegalaxy.eu), overlaid on the EU Natura 2000 protected-area network." . "The Po Delta — a Ramsar and Natura 2000 wetland on the Italian Adriatic coast and a key site for migratory and breeding birds — together with the nocturnal biodiversity it supports." . "How much artificial light at night intrudes on the Po Delta Natura 2000 protected area, when lit settlements are detected from VIIRS satellite night lights using an astronomy source-extraction tool run in Galaxy? This matters because artificial light at night is a documented stressor for the nocturnal birds, insects and bats that wetland refuges like the Po Delta support, and because it tests whether a tool from one discipline (astronomy) can be reused, unchanged, to answer an Earth-observation / biodiversity question." . .
