Mosaic of the territory of Catalonia made from rectified images and with atmospheric correction without (radiometric) topography correction, with a spatial resolution of 10 meters, captured in a specific month by the multispectral sensor (MSI) of the Sentinel-2 satellites within the framework of the Copernicus program. It contains information from the red, green, blue and near infrared bands of the electromagnetic spectrum. This mosaic is distributed in 4 by-products: 16-bit natural color orthoimage (red, green, and blue bands); 16-bit infrared orthoimage (near infrared, red, and green bands); 8-bit natural color orthoimage (red, green, and blue bands); and 8-bit infrared orthoimage (near infrared, red, and green bands).

Orthoimage representing the normalized difference vegetation index (NDVI), with a resolution of 1 m. This index makes it possible to estimate the quantity, quality and development of vegetation, based on the normalized difference between the radiation reflected in the infrared band of the electromagnetic spectrum with respect to the red band of the visible spectrum. This set of information is distributed in 2 by-products: Real NDVI orthoimage, where each pixel takes the real value of the index in question (between -1 and 1), in such a way that it facilitates exhaustive studies but requires advanced software; 8-bit NDVI orthoimage, where each pixel takes the value of the index in question but discretized to an integer range between 0 and 200, so that it facilitates an overview.
