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
