This tutorial demonstrates how to calculate MNDWI using ERDAS Imagine Model Maker or Spatial Modeller The Modified Normalized Difference Water Index (MNDWI) is is an index of open water features and produce much better result in comparison to NDWI Indices. MNDWI = (GREEN— SWIR)/(GREEN + SWIR) This index maximizes reflectance of water by using green ...
