About NDWI
The Normalized Difference Water Index (NDWI) is a remote sensing technique used to assess the presence and extent of water bodies or vegetation in satellite imagery. It is derived from the analysis of different spectral bands captured by sensors on satellites like Landsat 8. NDWI is calculated using the following formula:
NDWI = (Band Green - Band Near Infrared) / (Band Green + Band Near Infrared)
NDWI = (B03 - B05) / (B03 + B05)
In Landsat 8's context, the typical band combination used for NDWI calculation involves using the Green (Band 3) and Near Infrared (Band 5) bands. These bands are sensitive to the characteristics of water and vegetation, making them suitable for assessing water content and vegetation density.
The NDWI values range from -1 to 1, with higher values generally indicating the presence of water bodies, while lower values represent non-water surfaces like land. Here's how to interpret the NDWI values:
Values closer to 1: Typically represent water bodies such as lakes, rivers, and oceans.
Values closer to 0: Correspond to land surfaces, indicating the absence of or limited water content.
Negative values: Could indicate clouds, snow, or other non-water features. In some cases, negative values might also be used to detect shadows.
NDWI is widely used in various applications, including water resource management, land cover classification, environmental monitoring, and studies related to vegetation health.

Thank you sir very informative video, sir when I export data from GEE to Arc GIS its value increases, like maximum value increasing and minimum value decreasing in Arc GIS. every kind of data like LST, NDVI NDWI etc.

Hello, great video. what is the formula for calculating NDWI in MODIS?

[@TerraSpatial]

Hi, Thanks for your valuable comment. Please visit this website for NDWI using MODIS custom-scripts.sentinel-hub.com/custom-scripts/modis/ndwi/ and MODIS Spectral Bands lpdaac.usgs.gov/data/get-started-data/collection-overview/missions/modis-overview/

Please put your information also, thanks

i.e LST value in GEE ranges from 7 to 23 in the winter season. while the same image export to Arc GIS its ranges -5 to 50 degrees, even in the Summer season the the normal temperature range of my ROI is 23 to 34
