Hi,

I have a slope Majority raster layer created using zonal statistics on a LiDAR-derived slope map, where zones are soil map units.

I have a raster layer that shows, for each soil map unit, the low and high values typical of that map unit

 

The analysis I’d like to do is to compare where the slope Majority value of all pixels in a map unit of the first raster is outside the typical slope range as represented by the SLOPELO and SLOPEHI values in the other raster.  It should probably check for Majority < SLOPELO or Majority > SLOPEHI, and assign a value to the pixel based on outside or inside the field-mapped range.

 

My thinking is muddled on this.  Is it a raster calculator exercise?  Is the DIFF function useful?  Any help would be welcome.
