The boreholes database is an inventory of subsurface data in Catalonia through the collection of available geological and geotechnical survey information. The surveys are classified into three groups: surveys, penetrometers and trial pits.
The Soil Map of Catalonia 1: 250 000 is the result of the synthesis of the edaphological data available at the time of its preparation, in 2018. This process, carried out by the Cartographic and Geological Institute of Catalonia, has consisted of in the compilation, analysis and correlation of the cartographic information obtained in the different soil mapping works that have been executed in Catalonia since the 70's of the last century.
The Land Cover Map of Catalonia is a information set of high-resolution thematic cartography on the main types of land cover in the country, such as urban areas, agriculture, forestry or water bodies.
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 (OF-25C) 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 Soil Map at a scale of 1:25 000 is a map of edaphological content covering the entire surface of Catalonia, divided into 304 sheets defined according to the official 1:25 000 cut. It is a cartographic document that provides an overview of the edaphic structure of the country and, in summary, provides information on the distribution of soils in the territory, their morphologies, and their physical, chemical and biological characteristics. GT IV is the instrument for the realization of the Soil Map 1:25 000.
Synthesis of the hydrogeological macrounits into which the territory can be divided, called hydrogeological areas, and classification of the formations of the Geological Map of Catalonia 1:250,000 according to their lithological characteristics, type of porosity and consolidation.
The municipal database of addresses of Catalonia contains, for each municipality, the set of addresses of places where people can live or activities can be carried out, described by means of a couple of representative coordinates of the site, in two dimensions (2D), and attributes that specify the location and path. This set of data corresponds to the municipality of Sant Martí Vell.
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.
Delimitation of the hidrogeological units of Catalonia (aquifers, aquitards, aquicludes and aquifer systems), i.e. those parts of the lithosphere with distinctive parameters for water storage and conduction. The data model of this geoinformation is based on the technical specifications of geological data of the INSPIRE Directive (2007/2/CE).
The GeoBase of soils of Catalonia v1.0 is a database intended to store information on soils caught in the field and that necessary for generate soil maps of the territory of Catalonia at different scales, such as the Soil Map 1: 25,000 of Catalonia (MSC25M), or other maps that have been previously prepared (eg at scales 1: 25,000 and 1: 250,000). Contains information on soil profiles with varying levels of detail captured in the field (observations and pits), the composition on horizons, some of its physical and chemical characteristics as well as different types of soils that appear in an area, its spatial distribution.
