Thanks Marco, its very helpful.
I can get the total numbers pretty close if I use more decimals on my calculation converting pixel count to acres. And I think the bigger differences I was finding have to to with an offset of GIS layers used in a raster calculation- I'll fix that and see if it gets better. But either way its good for me to understand how SLAMM calculates area vs GIS, so thanks!
