The SOC is an integrated network of geometric grids coded for the rapid location of elements for rapid positioning in the territory, at any level of resolution. The data set is made up of two layers: the Quadrants layer (SOC5), formed by a grid of quadrants of 5 km on a side and the Sections layer (SOC1), formed by a grid of sections of 1 km on a side.

The dataset contains the polygons of known grasslands along the coast of Catalonia. The polygons have associated an attribute that indicates the type of community based on the species of phanerogams present: Posidonia oceanica; Cymodocea nodosa; Zostera noltii; Cymodocea nodosa i Caulerpa prolifera; Cymodocea nodosa, Zonstera noltii i Ruppia cirrhosa.

The dataset contains the coastline of Catalonia characterized for reporting the reliability of the grasslands in the 'Herbassars or prairies of marine phanerogams' dataset. If there is not known information in a section the line is not displayed. The degrees of reliability in which the line is classified are: Very high; High; Medium; Low.

Grids at different resolutions (1x1 km, 10x10 km, etc.) that express the UTM coordinates of Catalonia (ETRS89 zone 31 North) according to the Military Grid Reference System (MGRS).

The dataset contains the polygons of surrounding areas of grasslands or prairies of marine phanerogams. Bounding areas are zones in the sea near the shoreline where there is known to be grassland.

Names of administrative units, relief elements, hydrography, transport networks, points of interest and other geographical features of Catalonia. This data set is conforming to the technical specifications of INSPIRE Geographical names.

Reference topographic geoinformation with total or partial coverage of municipal management areas or geographic areas of specific themes that require detailed topographic information. It includes information related to the following layers: relief, hydrography, road network and other transport networks; buildings, constructions and facilities; land cover, toponymy and municipal inventories. This geoinformation can have different levels of resolution, corresponding to scales between 1:500 and 1:2000, although the most widely used is 1:1000.

Representation of the topography of Catalonia, that is, of the set of main landforms and morphological features that characterize the territory, at 1:250 000 scale.

Representation of the topography of Catalonia, that is, of the set of main landforms and morphological features that characterize the territory, at 1:1 000 000 scale.

Topographic database that covers all the territory of Catalonia, compiled in 2.5 dimensions. It contains data relating to the relief, the hydrography, the transportation networks, the settlement and the auxiliary infrastructures, the toponymy, the reference points and a reduced set of land cover and vegetation classes. The reference scale is 1:25 000.
