Abstract

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. Este trabajo representa un esfuerzo por hacer accesible y manejable en un formato estándar, un Sistema de Referencia Coordinado común y varias resoluciones, la información del Modelo Digital de Superficie normalizado de alturas de edificios para toda España -MDSnE2,5-distribuido por el Instituto Geográfico Nacional (IGN) y generado a partir de la primera cobertura LiDAR de ámbito nacional. A partir de la información original generamos una serie de capas en ETRS89-LAEA y diferentes resoluciones que van desde la original, píxeles de 2,5m x 2,5m hasta 1km x 1km, que constituye la malla de referencia estándar europea. Todas ellas pueden utilizarse para distintos análisis, en función del objetivo del trabajo. En cierto modo, este producto representa la versión nacional de la información sobre la altura de los edificios de la Capa Global de Asentamientos Humanos con cobertura mundial, distribuida por el Centro Común de Investigación de la Comisión Europea. Como subproducto, obtenemos otros dos tipos de información coherentes con la anterior. Una capa de edificación, que en su resolución original es binaria, 1/0, dependiendo de si el píxel se considera ocupado por un edificio o no, y que representa el porcentaje de la celda cubierto por edificios en capas de menor resolución. Y una capa de volumen edificado, que combina la información de la superficie edificada y la altura del edificio.
