Erdas Imagine MNDWI (Water) using Model Maker or Spatial Modeller for Landsat 8

Hi, can you explain me the conditional statement which is using in your videos. I have seen that you are using same conditional statement for both ndvi and mndwi. Is it same for all the indices or it may differ. Thanks

Thank you for this tutorial. I want to know how to extract the water bodies from the MNDWI image.

We need to first decide a proper threshold value .. and simple raster calculation will extract all the water bodies for you..
