I'm attempting to create a binary output raster in ArcMap based on an algorithm that uses three different reflectance index rasters I've already created from Landsat 5 data (mNDWI, NDVI, and EVI)the identify surface water pixels. The algorithm I need to apply is:
(mNDWI-NDVI>0 OR mNDWI-EVI>0) AND (EVI<0.1)
I need every pixel that the expression is true for to = 1, and every other pixel to = 0.
I tried stacking the three index rasters using the Composite Bands tool and then using the Band Arithmetic raster function, but the algorithm was invalid.
Is there a way to accomplish this in ArcMap?
