About the platform
One place, multiple layers of time and evidence.
NexaAtlas helps explain what is at a place, what was there before, and which sources support each piece of information. It brings together maps, names, administration, geology, mining, heritage and historical data without hiding provenance.
Why NexaAtlas exists
The core product question is: what did I find, what is around this location, and why could an object be here?
The platform is designed to support exploration and context, not to turn correlation into certainty.
Where you can explore places
The most detailed information covers Poland. Selected places in Austria, Czechia, France, Germany and Slovakia also have basic map and place information.
A map that's easy to explore

The source is part of the answer
Information without provenance has limited value. NexaAtlas shows the available data sources and supporting information. Conflicts between sources should remain inspectable rather than being silently overwritten.
What the platform keeps separate
- Source-backed fact - information reproduced from a specific source.
- Inference - an interpretation that is not the same as a source record.
- Reconstruction - a reconstructed view that requires explicit labeling and evidence.
- Uncertainty - missing precision or disagreement is not hidden.
Location privacy
Exact coordinates of private finds and sensitive sites are not automatically published. Public geometry has a separate controlled boundary and may deliberately be generalized.
No automatic certainty
Spatial proximity does not prove origin, ownership or causality. Likewise, a source-record version date is not automatically the real-world creation date of a mapped object.
