The indexes NDWI and MNDWI are use to identify waterbody. Can I use these index to identify wetland also? Thank you for advance.
Dear Kévin Ella-Ekabane,
To identify wetland areas in Landsat imagery, a combination of spectral indices is highly effective. Water-sensitive indices like NDWI and MNDWI are crucial for highlighting water features, as you mentioned, while vegetation indices such as NDVI help capture wetland vegetation characteristics. For more specialized detection, indices like WAVI (Water Adjusted Vegetation Index) or WITI (Wetland Inundation Tendency Index), designed specifically for wetland environments, can provide enhanced accuracy. This multi-index approach allows for a comprehensive assessment of wetlands, capturing both their aquatic and vegetative components, and thereby improving the overall accuracy of wetland identification and mapping.
I hope this will help!
Good Luck!
Yes, NDWI (Green - NIR) and MNDWI (Green - SWIR) can be used to identify wetlands in Landsat imagery, as they highlight water bodies.You should also consider using NDMI for a clear indication of wetlands.
