## About

GEUS (De Nationale Geologiske Undersøgelser for Danmark og Grønland) provides programmatic access to national geoscience collections. Key services include the nationwide Jupiter database (water supply wells, groundwater chemistry, borehole geology), the GERDA geophysical database, MARTA marine data, and seismic surveys. Services are exposed through OGC-standard WMS, WFS, and downloadable datasets.

## Agent use cases

- Query borehole profiles, geological strata, and well construction data from the Jupiter database
- Fetch historical groundwater levels, drinking water quality samples, and chemical analyses
- Integrate geophysical survey layers (GERDA) into subsurface analysis pipelines
- Download geological maps and shallow subsurface model layers for engineering assessments

## Notes

Publicly accessible and free to query via standard OGC WMS/WFS capabilities endpoints. Data is licensed for open public and commercial reuse with attribution.
