1) Build raster attribute table (if it doesn't already exist) 2) Create new field to store the area 3) Use field calculator to calculate the areas using the "count" field and the cell size of your raster: area = count * cellsize^2 This will be in square meters, assuming that your cell size is in meters. You can divide by 1,000,000 if you'd rather have ...
