I have to use the NLCD 2011 dataset and I am trying to understand the "no change" class. This class is not defined in any of the legend descriptions (Anderson classification).
What is the no change class in NLCD 2011?
Multi-Resolution Land Characteristics (MRLC) consortium has a couple of different datasets of changes (2001-2011 & 2006-2011). Depending on what data you are using, you are most likely looking at changes from one of those years (my assumption is 2006, but there is always some outdated stuff lurking on the internet waiting to be downloaded).
