I've been trying to find orthoimages with 4 bands for a couple of counties in California. I managed to download some from the GeoSpatial Data Gateway from the USDA (NRCS), but they all only have 3 bands even though it says that images from after 2010 were acquired with 4 bands. (They are called 2012 National Ag. Imagery Program Mosaics.)
I've tried so many other sites - USFS, USGS, etc. to get 4 band images (that aren't massive) to no avail. I feel like EarthExplorer from USGS possibly has what I need, but I can't figure out which data is what I'm looking for since they have so many options. Can someone please advise on how I can get this info? The pictures I downloaded from the USDA are perfect and beautiful if they just had the 4 bands.
