NLCD 2001 from-to 2016 Land Cover Change Pixels (ALASKA)

The Alaska from to change layers represent all pixels in Alaska with combined pre-and post classification number. For instance, and unchanged water area is represented as class 11 in both years. This would result in a pixel value of 1111. Any change between the pre-and post-years would have the same values. For instance, a change from water to ice and snow would use classes 11 and 12. This pixel value would be represented as 1112. This particular notation for change is only available for Alaska as there are only three Landcover dates. For the seven dates of conus, this would result in 49 potential combinations. A change index representing all change through all years is provided for conus.
