Adds an algorithm that detects thick and thin clouds in Sentinel-2 L2A imagery as an openEO UDP, using the Braaten-Cohen-Yang (BCY) cloud detector. The openEO process is adapted from a SentinelHub BCY cloud detection evalscript, applying threshold tests on the green band, NDGR (green/red normalized difference), and a SWIR constraint to flag thick and thin clouds while reducing snow misclassification. The result is a color-coded RGB (blue = thick cloud, red = thin cloud, natural color = clear).
The openEO process is running on Copernicus Data Space over the spatial extent of Pitigliano, Tuscany, Italy on 2025-10-01 to 2025-10-31.
