Advanced Water Detection in Google Earth Engine | DSWE Method (Sentinel-2, Part 3)

Part 3 of the water detection series in Google Earth Engine. In this video, we go beyond NDWI and build a highly accurate water mask using DSWE — Dynamic Surface Water Extent. DSWE uses multiple spectral indicators to classify water more reliably: • NDWI (Green–NIR) • MNDWI (Green–SWIR1) • NDMI (NIR–SWIR1) • NIR absorption • SWIR1 reflectance • SWIR2 dark-water detection This method outperforms simple NDWI thresholding and works extremely well in: • urban areas • deep and dark water • building shadows • wetlands • mixed pixels • rivers with vegetation 📌 Series Structure • Part 1 — Cloud-free Sentinel-2 composite • Part 2 — NDWI basic water extraction • Part 3 — DSWE advanced water mask (this video) 📄 Code Availability All code blocks for NDWI and DSWE are placed in the description of Part 2 to keep the entire series clean and consistent. 👉 Part 2 (NDWI Water Mask):    • NDWI Water Detection in Google Earth Engin...   🔖 Hashtags #GoogleEarthEngine #DSWE #Sentinel2 #RemoteSensing #WaterDetection #GIS #EarthObservation #GEE #Geospatial #Mapping #SatelliteData
