Hello all,
I need to calculate the difference in area in a habitat raster (or polygon, I have both) between one sea level rise scenario and a baseline of no change. I have used Raster Calculator to subtract the sea level rise value from my DEM raster. Now I need to calculate how much of my habitat still exists under the new sea level. So I need to calculate how much of my new habitat extent is > or = 0 in elevation. I'm working with a floating point DEM raster. Any suggestions on an approach for this?
Thanks kindly,
Sally
