# Data sources and licences

> Index of the TerraLab docs for agents: [llms.txt](https://terra-lab.ai/docs/llms.txt). Every docs page is also served as markdown: add .md to its URL.

TerraLab serves open data. Every result lists its `sources` with their licence, and every file you download keeps that licence and its attribution. You pay for the service, never for the data.

## Main sources

| Source | Used for | Licence |
| --- | --- | --- |
| OpenStreetMap | Roads, places, waterways, land use, transit, routes and travel-time areas | ODbL 1.0 |
| Overture Maps | Buildings, places, addresses and boundaries | ODbL or CDLA Permissive 2.0, by theme |
| Copernicus DEM | Elevation, profiles and contour lines, worldwide at 30 m | Copernicus DEM licence, free with attribution |
| Copernicus Sentinel-2 | Satellite images worldwide at 10 m | Copernicus data, free with attribution |
| IGN and DGFiP | French addresses, cadastral parcels, urban plan zones, building heights and aerial photos | Licence Ouverte 2.0 |

Hosted datasets from the TerraLab catalogue ([find_datasets](https://terra-lab.ai/docs/api/find_datasets), [extract_dataset](https://terra-lab.ai/docs/api/extract_dataset)) each keep their own licence, quoted with them.

The full list of licences and the attribution to show is on [Data licences](https://terra-lab.ai/legal/data-licences).

## Attribution

When you publish a map or a dataset built from a TerraLab result, show the credits from its `sources`. For OpenStreetMap data, that is "© OpenStreetMap contributors"; ODbL also asks that a database you share stays under ODbL.

## Limits

- Up to 20,000 features per extract, about 1 km around a town centre.
- Elevation at 30 m; contour areas up to about 10 × 10 km.
- Files up to 50 MB, lists up to 100 addresses.
- Parcels, zoning, building heights and IGN photos: France only.
- Routes through 25 places; travel areas up to 120 min or 200 km.
- Satellite images up to 20 × 20 km at 10 m.
- Approximate: not for navigation, surveying or legal boundaries.

Each tool page in the [API reference](https://terra-lab.ai/docs/api) gives the exact range of every parameter.

## Privacy

- Only what the request needs is sent: a place, an area or a file.
- Logs keep the tool, its status and duration, never your question. The requested area is kept 30 days, with no user identifier.
- Files are processed in memory, never stored.
- Never sold, never used to train AI.

Read the [privacy policy](https://terra-lab.ai/privacy-policy) and the [API terms](https://terra-lab.ai/legal/api-terms).
