Learn how to calculate the Automated Water Extraction Index (AWEI) using Sentinel-2 Surface Reflectance imagery in Google Earth Engine (GEE). This tutorial demonstrates a complete workflow for detecting water bodies in Rahta region (2022) with minimal cloud cover.
📌 What you'll learn:
Loading Sentinel-2 SR data
Filtering by date and cloud percentage
Selecting spectral bands (Green, NIR, SWIR1, SWIR2)
Applying the AWEI formula in GEE
Visualizing water features using color palette
🚀 Whether you're working on flood mapping, surface water monitoring, or land use research — this video gives you a reusable code template for accurate water body detection.
