Adapting one Earth model to many maps
Prithvi-EO-2.0 is a geospatial foundation model that can be adapted to Earth-observation tasks such as flood mapping, crop classification, and land-use analysis.

The claim in context
The human problem
Organizations need current maps of floods, crops, and land change but may have little labeled local data.
The prior constraint
Each mapping task often required a separately trained model and substantial satellite-data preparation.
AI’s actual role
The pretrained model converts multispectral satellite time series into representations that a smaller labeled dataset can adapt to a local mapping task.
The documented result
NASA and IBM publish model variants, code, examples, and task evaluations through the Prithvi repository and model cards.
Why it may matter
A shared geospatial base can lower the starting cost of local mapping, provided teams validate it against the place and decision at hand.
Limitations
- The Prithvi-EO-2.0 repository code is MIT and the named 300M checkpoint is Apache-2.0, but those terms do not make every satellite input freely redistributable. Performance can shift by region, sensor, season, and local ground truth.
- NASA and IBM document the public artifacts and research tasks. This broader mapping record is distinct from Bright's separate Prithvi in-orbit demonstration.
