Pounce Atlas is an open-source explorer for geographic datasets. Its demo data is fictional, but parts of it come from other sources with their own licences. This post separates those licences and gives attribution text you can reuse. It is information, not legal advice.
Disclosure: AI assisted with drafting this post. Pounce prepared it from the repository's third-party notices and licence file.
The short version
- Application code and documentation contributed to the repository: MIT licence.
- Invented business and venue attributes in the demo files: CC0 1.0.
- Place names and approximate centre coordinates from GeoNames: CC BY 4.0. Attribution is required.
- Boundary geometry for South Africa: derived from Natural Earth 1:10m admin-1 boundaries, simplified for display. Natural Earth map data is public domain.
- Interface font (Inter): SIL Open Font License 1.1.
- Three.js: MIT licence.
Attribution text you can reuse
Place centres: GeoNames, CC BY 4.0. Selected South African place references associated with fictional example records; coordinates indicate approximate centres. Boundary geometry: Natural Earth, public domain.
What the MIT licence does not cover
The MIT licence does not relicense third-party assets, production data or trademarks. Pounce's name and marks are not licensed as trademarks by MIT, so do not imply endorsement or an affiliation that does not exist.
Where the fictional examples come from
The two fixture files, public/data/demo.json and public/data/venues.json, contain invented business and venue names, attributes and events. Their town names and approximate centre coordinates come from a GeoNames South Africa extract downloaded on 21 October 2026.
