Vegetación por satélite en España · NASA · bosques.eu

Vegetación por satélite en España · NASA · bosques.eu is a free, registration-free search tool that uses NASA satellite imagery to show whether any Spanish municipality is greener or less green than in 2001. It measures vegetation cover across entire municipal areas, including crops and woodland, using NDVI data. The site organizes its data hierarchically by Spanish autonomous communities, provinces, and municipalities, listing all 17 regions along with the autonomous cities of Ceuta and Melilla.

The website allows users to compare two different time periods, such as two summers or the before and after of a fire, by selecting two distinct dates. Users can choose to measure the entire municipality term or only the wooded area, and compare summer to summer or two months apart. The site also provides options to locate a fire limit and view real images alongside vegetation data.

The platform uses NASA MODIS data with a resolution of approximately 250 meters per pixel to measure the Normalized Difference Vegetation Index (NDVI). While the actual photo is only used for location, the precise metric is the greenness level, which can be distorted by clouds, snow, or drought. The site explicitly states it measures the change in vegetation, not the cause, which could be a fire, drought, logging, harvest, or new planting.

The site provides a 'Mapa de cambios' (Change Map) feature that shows the difference in vegetation between two selected dates. Users can also view 'Imagen real' (Real Image) and 'Imagen actual' (Current Image) to see the actual satellite photos alongside the calculated NDVI changes. The interface allows users to toggle between more vegetation, less vegetation, more brown, and more green visualizations.

The platform integrates data from multiple external sources, including Copernicus for temperature and rainfall reanalysis via Open-Meteo, and EFFIS for fire data. It also utilizes NASA GIBS for NDVI, OpenStreetMap, and Esri for satellite imagery. The site explicitly mentions that it is an independent project with no affiliation to the NASA or official organizations.

The site displays current statistics such as the percentage of surface affected by fires of 50 hectares or more, the percentage of soil with trees (copas del 30% o más), and average temperatures. For example, as of November 12, 2026, the site reported 295,734 hectares affected by fires, a 148% increase from the previous year. It also shows data on rainfall and temperature compared to 30-year averages.

The site includes a 'Guías' (Guides) section that covers topics such as how to read the NDVI index, why a town might appear drier, and recovery after a fire. It also provides a 'Método: cómo se mide' section to explain the measurement process. Additionally, the website offers a 'Contexto' section that links to external sources like AEMET for climate and drought, EFFIS for fires, and MITECO.

The website explicitly states that it is a free service with no registration required. Users can access all features, including the search tool and map comparisons, without any cost. The site also mentions that the weekly email summary is free and that the search tool has no registration requirements.

The site includes a 'Cómo funciona' (How it works) section that explains the process step by step. It also provides a 'Sobre el proyecto' (About the project) section. The website footer includes links to 'Privacidad' (Privacy) and 'Términos de uso' (Terms of use) to inform users about data handling and usage rules.
