NASA STAC Catalogues

[RichardScottOZ]

Hi All,

Has anyone had a go and these and wrangling into stackstac?

I think @scottyhq and @rmg55 have been a little bit? Check out https://gist.github.com/scottyhq/c4a4e889b58a0a153dd5fb18bad9f3e8 and https://github.com/rmg55/CloudDAAC_Binders/blob/main/s3_v_http.ipynb

Thanks Gabe - saw an older one of his that was giving me a zero result, but that is likely a catalogue.

Don't think I have seen those ones yet, so thanks for that.

and the bbox format is a string in one, I might have been using a list, giving problems

bbox = [-53.0172669999999968,-9.5331669999999988,-48.4956669999999974,-3.1035670000000000']

bbox = '-53.0172669999999968,-9.5331669999999988,-48.4956669999999974,-3.1035670000000000'

The NASA CMR STAC endpoint is very promising, but it is also somewhat experimental. There are a number of open issues to keep an eye on here https://github.com/nasa/cmr-stac . The endpoint is currently updated every two weeks or so, so your mileage may vary.

Thanks Scott

Also presumably what is USA and not USA I imagine?

[RichardScottOZ]

Anyway, borrowed Scott's gist for a quick look :-

Comparison to element84 numbers returned - which had a lot missing for the bit of Brazil I was looking at yesterday.

I went with datetime as an explicit string, too

[RichardScottOZ]

and they don't currently all work it would seem?

https://cmr.earthdata.nasa.gov/stac/

[RichardScottOZ]

an error seeming slightly odd python SSLError: HTTPSConnectionPool(host='cmr.earthdata.nasa.gov.s3.amazonaws.com', port=443): Max retries exceeded with url: /stac/LARC_ASDC/collections?limit=500 (Caused by SSLError(SSLCertVerificationError("hostname 'cmr.earthdata.nasa.gov.s3.amazonaws.com' doesn't match either of '*.s3.amazonaws.com', 's3.amazonaws.com'")))

@RichardScottOZ I'm having a hard time following what you're trying to do. If you're able to consolidate the comments into a single one at the top, or flesh out the context and error you're getting in a github issue in https://github.com/nasa/cmr-stac, or https://github.com/sat-utils/sat-search we could troubleshoot there.

[RichardScottOZ]

Ok, will do. At the moment, I was more just having a look at the 'get a quick list of what is available' capability: re element84 missing lots of Brazil data.
