Provisional data disclaimer

USGS labels recent real-time readings provisional until reviewed, and the disclaimer bars their use in legal or regulatory decisions until approval.

The restriction overlays an otherwise public-domain data source.

In this catalog it appears concretely: - USGS Water Services — "most recent data marked provisional under the USGS Provisional Data Disclaimer". - same — "Provisional data must not be used for legal/regulatory decisions until approved".

same is the second reference point worth knowing: "Provisional data must not be used for legal/regulatory decisions until approved". Reading the two together shows how much variation sits underneath one shared label.

License language decides what you may ship to customers. Misreading it has ended product launches, and the gap between free to view and free to redistribute is where most of those failures begin.

The failure mode is concrete: a source can carry the Provisional data disclaimer label while differing from what you need on exactly the dimension that matters — most recent data marked provisional under the USGS Provisional Data Disclaimer. Comparing two sources on that line usually settles the choice faster than any feature matrix.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and USGS Water Services lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open USGS Water Services and confirm its record — "most recent data marked provisional under the USGS Provisional Data Disclaimer" — against the files you actually receive.
2. Open same and confirm its record — "Provisional data must not be used for legal/regulatory decisions until approved" — against the files you actually receive.
