How to Calculate NDWI (Normalized Difference Water Index) in ArcGis 10.8 Step-by-Step

Video Title: How to Calculate NDWI (Normalized Difference Water Index) Step-by-Step Description: Welcome back to GIS with Wr Khan! 🌍💧 In this step-by-step tutorial, we dive into the Normalized Difference Water Index (NDWI)—one of the most powerful tools in remote sensing for extracting and mapping water bodies from satellite imagery. Whether you are working on a hydrological project, monitoring flood extents, or just learning geospatial analysis, this video will walk you through the entire calculation process from start to finish. What you will learn in this video: • What NDWI is and the mathematical formula behind it (Green & NIR bands) • How to prepare the right satellite imagery bands (e.g., Landsat or Sentinel) • Step-by-step NDWI calculation using the Raster Calculator in [ArcMap 10.8 / ArcGIS Pro / QGIS / Google Earth Engine] • How to classify and symbolize the final output to perfectly isolate surface water ⏱️ Video Chapters (Timestamps): 0:00 - Introduction to NDWI & Use Cases 1:15 - Understanding the NDWI Formula 2:30 - Adding Satellite Data to the Workspace 4:00 - Executing the Raster Calculator tool 6:45 - Symbolizing & Highlighting Water Bodies 8:30 - Final Map Layout & Export 🔗 Resources & Links: • Download free satellite data (USGS EarthExplorer): [   • How to Download Landsat 8 Imagery from USG...  ] • Subscribe to the channel for more GIS tutorials:    / @giswithwrkhan   👍 If you found this tutorial helpful, please hit the LIKE button, drop your questions in the COMMENTS, and SUBSCRIBE to stay updated on the latest mapping and remote sensing workflows.
