explain how NAIPs are indexed on the S3 bucket

[andrewljohnson]

I don't understand how I can make an index of the NAIP bucket on S3. The parameters are as follows: ['md', '2013', '1m', 'rgbir', '38077']

I understand all the parameters but the last one... I assume that is some sort of grid or ordinal ID.

If I knew what the final parameter was, I could write a script to get training data from any state/year. Now it's limited to a certain place in Maryland, around Washington DC.

AFAIK this is the FIPS code, as stated on the appendix [page 18] here...

Thanks @brunosan 👍

Btw, I noticed that at the linked USDA page on the wiki article you can get plain text codes, but I couldn't find the matching example above.

The codes in the filenames were not matching up to FIPS as far as I could tell, so I was wondering what was up.

Maybe this is moot though. I think the NAIPs need to be downloaded to get exact geo information. I don't think even the FIPS code and other filename info could be mapped to a good bounds for each file.

I think I'll change the scripts to work with any given US state (plus year) for now... instead of trying to exactly geo-index the whole bucket. That should serve my needs for doing some geographically disparate analyses.
