Web App Uses SAR to Visualize Kerala floods


n conversation with a scientist who has made a web app to visualise the flooding in Kerala

MD Madhusudan, Scientist at Nature Conservation Foundation, Mysore, discusses the web app he made to help visualise and assess flooding extents in the tragedy of the Kerala floods. Built in a day and finetuned in another two, the app uses data from a radar satellite called Sentinel-1, launched by the Eurpoean Space Agency, and was made entirely on Google Earth Engine, which combines a multi-petabyte catalogue of satellite imagery and geospatial datasets with planetary-scale analysis capabilities. Earth Engine is freely available for scientists, researchers, and developers to detect changes, map trends, and quantify differences on the Earth’s surface.
