This study analyzes the sediment loss associated with the removal of Syringodium filiforme berms from 10 beaches in the Dominican Republic. The results show that approximately 63.8% of the removed volume corresponds to interspersed sediment. This type of management has a continuous morphological impact, affecting the stability of the system's sediment balance.

Description of the earth's surface (of Catalonia) by its (bio-)physical characteristics, according to the Land Cover Map of Catalonia (MCSC) classification. This data set is conforming to the technical specifications of INSPIRE Land cover.

The metropolitan multi-beam bathymetry is a representation of the submerged part of the surface of the coastal strip. The seabed is represented with a very dense 3D point cloud with X, Y and Z coordinates. It is measured with a multi-beam echosounder, and provides very detailed data that can represent submerged elements of relatively small dimensions (even less than a meter).

The Land Cover Map of Catalonia is an 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 metropolitan topobathymetric elevation model is a representation of the surface of the coastal strip, both the emerged part (dry beach) and the submerged part, up to an approximate depth of between 15 and 20 meters. The depth is represented with a regular grid of 1 meter pixel size. The emerged part is measured with topography methods, the first meters of the submerged part are measured with a single-beam echosounder and the rest is measured with a multi-beam echosounder, which provides very detailed data of the seabed.

Metropolitan topobathymetric cartography is a representation of the surface of the coastal strip, both the surface (dry beach) and the submerged part, to an approximate depth of between 15 and 20 meters. The depth is represented in the surface part with contour lines and in the submerged part with isobaths, both with an equidistance of 0.5 meters. No planimetric element is represented, only the relief of the seabed.

The study examines human influence on the evolution of beach-dune systems in the Balearic Islands, focusing on afforestation with Pinus halepensis. Historically, actions have been taken to stabilize these areas, significantly impacting the morphology and dynamics of the systems. Through a historical review and analysis of 31 such systems, it is evident that the presence of Pinus halepensis is largely associated with human interventions, significantly affecting vegetation structure and biodiversity conservation.

The information set of surfaces affected by wildfires contains the delimitation of areas affected by forest fires, considered with strong environmental impact, described by its representation in two dimensions in scale 1:50,000 and attributes that describe its semantic.
-
Synthesis of the geological constitution of Catalonia through the cartographic representation of lithostratigraphic geological units, major structural elements (unconformities, faults and folds) and types of contact between units. The situation of the soundings carried out for the exploration of hydrocarbons is also included.

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.
