[ES] La Base de Datos de Índices de Vegetación para la Península Ibérica y las Islas Baleares (VIIB) proporciona series temporal extensas y detalladas de índices de vegetación—NDVI, kNDVI, SNDVI y SkNDVI— con una resolución temporal quincenal y una resolución espacial de 1.1 km, cubriendo el periodo desde 1981 hasta la actualidad. Específicamente diseñada para la Península Ibérica y las Islas Baleares, esta base de datos permite la exploración de patrones de vegetación tanto históricos como actuales, así como la detección y estudio de anomalías a lo largo de la región durante más de cuatro décadas. Con actualizaciones quincenales, proporciona un recurso continuo y actualizado para comprender los cambios y tendencias en la vegetación. La base de datos integra conjuntos de datos de NDVI—Sp_1km_NDVI, MYD13A2 y VNP13A2—derivados de los sensores satelitales AVHRR, MODIS y VIIRS, respectivamente. Estos productos NDVI han sido sometidos a un proceso de armonización riguroso, asegurando la consistencia temporal de las series temporales.
[EN] The Vegetation Indices for the Iberian Peninsula and Balearic Islands (VIIB) Database offers comprehensive long-term time series of vegetation indices—NDVI, kNDVI, SNDVI, and SkNDVI—with a bi-weekly temporal resolution and a spatial resolution of 1.1 km, spanning from 1981 to the present day. Specially designed to encompass the Iberian Peninsula and Balearic Islands, this database facilitates the exploration of both historical and contemporary vegetation patterns and anomalies throughout the region over more than forty years. With bi-weekly updates, it provides a continuous and up-to-date resource for understanding vegetation changes and trends. The database integrates NDVI datasets— Sp_1km_NDVI, MYD13A2 and VNP13A2—derived from AVHRR, MODIS and VIIRS satellite sensors, respectively. These NDVI products have undergone a rigorous harmonization process, ensuring the temporal consistency of the time-series.
[EN] It contains 4 files, one for each vegetation index—NDVI, kNDVI, SNDVI, and SkNDVI—in netcdf format. Multiple options exist for reading and manipulating netCDF files (.nc), with the most common including GIS applications like QGIS and ArcMap, specialized applications such as Panoply (https://www.giss.nasa.gov/tools/panoply/), and dedicated libraries such as ncdf4, raster, or terra in R, as well as netCDF4 or xarray in Python, among others.
