I seem to recall USGS Earthexplorer providing current and historic 4 band NAIP imagery over the last few years. It appears that these data have been migrated to the National Map. However, the National Map only appears to have 2011 4-band NAIP imagery. The USDA FSA points users to the NRCS Geospatial Data Gateway, although these downloads only appear to be 3 band images without the nIR band.
- What are the best sources for downloading historic and current 4 band NAIP imagery at 1m spatial resolution?
- Are there any Oregon specific download sites?
