Here you can find the Digital Terrain Model -DTM- used to create visibility and network paths. Our DTM has been built merging several sheets -666, 667, 668, 694, 695, 696, 720, 721, 722- of the Digital Terrain Model known as DTM05 that can be downloaded from the Centro Nacional de Información Geográfica -CNIG- "[Centro de Descargas](https://centrodedescargas.cnig.es/CentroDescargas/locale?request_locale=en)" -download hub-, the Spanish Government official provider of Geographic Information. The original product is described as a Digital Terrain Model 1st Coverage with 5 m grid spacing. The nine sheets were merged and cropped to a final DTM of 7600 by 5600 with the following corner coordinates: Upper Left ( 680000.000, 4403000.000) Lower Left ( 680000.000, 4375000.000) Upper Right ( 718000.000, 4403000.000) Lower Right ( 718000.000, 4375000.000) Center ( 699000.000, 4389000.000)

This DTM is part of the supplementary material of a forthcoming paper in Zephyrus "Analysing the sacred landscape in the Iberian Iron Age: GIS, caves and ritual performance" by Sonia Machause López and Agustín Diez Castillo.
