Un índice de rugosidad del terreno a escala municipal –updated–Superficie 2D versus superficie 3D y rugosidad

Résumé

The value of the roughness of the terrain, which expresses a characteristic related to the roughness or escarpment of a certain territory, has been widely used in various branches of science to mainly explain behavior of fauna and location of flora. In the present work, a method of calculating a roughness index of easy interpretation and integration is exposed for the 500,000 km² of the Spanish territory. Next, an analysis of its relationship with altitude is developed, as well as the current and historical distribution of the population at the municipal level, detailing a ranking of the 25 municipalities with the highest roughness in Spain.
