Bosques · Terms of Use

Last updated: 17 July 2026

1. What this service is

Bosques is a free, informational web tool that estimates whether the vegetation of a Spanish municipality appears greener or less green between two years, using public satellite data (NASA MODIS NDVI at ~250 m resolution) analyzed in your browser. It is provided by bosques.eu, operating the website bosques.eu as an individual (contact: hola@bosques.eu), the same operator identified in the privacy policy.

By using the site you accept these terms. If you do not accept them, do not use the site.

2. The verdicts are estimates · critical disclaimer

Everything this tool shows is an automated estimate, not a measurement certified by anyone.

• Verdicts are derived from satellite vegetation greenness (NDVI). Greenness is not tree count, forest cover, or ecological health. Crops, scrub, and irrigation all move the number.
• Results are affected by clouds, snow, drought timing, sensor aging, and the coarse ~250 m resolution (a small village spans only a handful of pixels). Changes under 2% are within noise.
• Verdicts are not scientific evidence, not official environmental data, and not valid for legal, administrative, insurance, land-use, subsidy, or investment purposes. They must not be cited as proof of deforestation, reforestation, or compliance with any obligation.
• If you need reliable figures, consult official sources (IGN, Copernicus/EEA, MITECO, EFFIS) or a qualified professional.

3. No warranty; limitation of liability

The service is provided "as is" and "as available", without warranties of any kind, express or implied · including accuracy, completeness, fitness for a particular purpose, or uninterrupted availability. The underlying data services (NASA GIBS, Opendatasoft, OpenStreetMap/Nominatim) are third parties we do not control; any of them may change, rate-limit, or disappear, and the tool may stop working without notice.

To the maximum extent permitted by law, the operator is not liable for any damage or loss arising from use of, or reliance on, the site or its verdicts, including decisions taken (or not taken) based on them.

Nothing in these terms excludes or limits liability that cannot be excluded under applicable law, including liability for willful misconduct (dolo) or gross negligence under Spanish law, or statutory consumer rights that are non-waivable.

4. Acceptable use

• Do not abuse the site or, through it, the third-party services it relies on (e.g., automated bulk scraping through our page against those services' usage policies · notably the OSM tile and Nominatim usage policies).
• Do not present the tool or its output as endorsed by NASA, IGN, the OpenStreetMap Foundation, Opendatasoft, or any public authority. Use of NASA imagery does not imply NASA endorsement.
• Do not remove or obscure the data attributions in the footer and methodology dialog.

5. Data sources, attribution, and licenses

The app displays and processes data from the following sources. If you reuse screenshots, figures, or data obtained through this app, you must preserve these attributions and comply with the underlying licenses:

The NDVI percentages and diff maps are derived works computed in your browser from NASA data; they inherit the caveats in §2 and the attribution duties above.

6. Intellectual property of the app

• The Bosques code is © 2026 Ismael Cruces. All rights reserved.
• The Bosques name and any logo are not licensed for third-party use.
• Original text and methodology copy on the site is © 2026 Ismael Cruces. You may quote short excerpts for journalistic or educational purposes with attribution and a link to bosques.eu.
• Third-party components: Leaflet (© Volodymyr Agafonkin and contributors, BSD-2-Clause) · its notice must be preserved if the code is redistributed.

7. Linking and journalistic use

You may link to the site, including deep links (share URLs). Journalists may cite verdicts provided the figure is presented as a satellite-based estimate with its caveat (the verdict card's caveat text is written for exactly this) and attributions in §5 are respected.

8. Changes, suspension, termination

This is a free service; we may modify or discontinue it at any time without liability. We may update these terms; the current version is always at this URL with its date.

9. Governing law

These terms are governed by Spanish law. Disputes go to the courts of the operator's domicile in Spain · except where consumers have a statutory right to their own domicile's courts, which is unaffected. If any clause is found invalid, the rest remain in force.
