This work represents an effort to make accessible and manageable in a standard format, a common Coordinated Reference System and various resolutions, the information of the normalised Digital Surface Model of building heights for the whole of Spain -MDSnE2,5- distributed by the National Geographic Institute (IGN) and generated from the first nationwide LiDAR coverage. From the original information we generate a series of layers in ETRS89-LAEA and different resolutions ranging from the original one, pixels of 2.5m x 2.5m up to 1km x 1km, which constitutes the standard European reference grid. All of them can be used for different analyses, depending on the objective of the work. In a way, this product represents the national version of the building height information from the Global Human Settlement Layer with global coverage, distributed by the Joint Research Center of the European Commission. As a by-product, we obtain two other types of information consistent with the previous one. A built-up layer, which in its original resolution is binary, 1/0, depending on whether the pixel is considered occupied by a building or not, and which represents the percentage of the cell covered by buildings in lower resolutions layers. And a built-up volume layer, which combines the information from the built-up surface and the building height.
