Category: water
Sensor: SuperView-2
Provider: SPACEWILL
Bands Used: 2
Description
The Modified Normalized Difference Water Index (MNDWI) was developed by Xu (2006) as an improvement over the original NDWI. By substituting the NIR band with SWIR, MNDWI can enhance open water features while efficiently suppressing noise from built-up areas, vegetation, and soil. This makes it particularly suitable for water detection in urban environments.
