There are a couple of places to get NLCD data. One place that I use is the NCLD site (www.mrlc.gov/nlcd11_data.php). It is big, but you can mask out the areas you want once you get the base image. The other place you can go is the National Map (viewer.nationalmap.gov/basic/) and get the area you want. You'll still need to manage the data (mosaic, mask, etc.) to get your AOI.
from where did you download landuse data NLCD has 100 values
