    The orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in the entire surface of the image, being a geometric representation on scale of the terrestrial surface. It is a orthophoto with a resolution of 25 cm generated from images with a pixel resolution variable according to the zones. The color orthophoto provides information about the visible area of the electromagnetic spectrum. Shows the combination of RGB bands that correspond to the Red, Green and Blue channels, a combination called "natural color". The expedited orthophoto has not been edited, so it may present certain artifacts (clouds, shadows, stretches, etc.).

It is a orthophoto with a resolution of 25 cm generated from images with a pixel resolution variable according to the zones. The infrared orthophoto provides information about the infrared area of the electromagnetic spectrum. Shows the combination of IRC bands that correspond to Infrared, Red and Green channels, a combination called "false color. The expedited orthophoto has not been edited, so it may present certain artifacts (clouds, shadows, stretches, etc.).

    The Territorial Topographic Referential constitutes the topographic base of reference with total coverage of the territory of Catalonia. Includes information regarding the following layers: relief; hydrography; roads and other transport networks; buildings, constructions and facilities; soil coverages; and geographical names.

    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.

  • The Territorial Topographic Referential constitutes the topographic base of reference with total coverage of the territory of Catalonia. Includes information regarding the following layers: relief; hydrography; roads and other transport networks; buildings, constructions and facilities; soil coverages; and geographical names. This organization of information facilitates an agile and versatile use of data, as it allows to work with all the information at once, or make selections by layers of information or by territorial areas, as well as changes in symbolization. In order to guarantee the most widespread use possible, this version is distributed in Geopackage format, exploitable from free software, and also as a Geodatabase, closely linked to GIS. The file contains vector data organized in different thematic layers, as well as metadata tables and descriptions of attribute values. The files incorporate a stylization, for the free software QGIS in the case of the Geopackage, and for the ArcGIS Pro in the case of the Geodatabase. This distribution is ready to work on scales close to 1: 5,000.
