Here you can find the Digital Terrain Model -DTM- used to create influence areas. Our DTM has been built merging several sheets -Alacant, Albacete, Castelló, Cuenca, Teruel & València- of the Digital Terrain Model known as DTM200, 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 200 m grid spacing. The nine sheets were merged and cropped to a final DTM of 1218 by 1184 with the following corner coordinates: Upper Left ( 550500.000, 4507500.000) ( 2d24' 7.52"W, 40d43' 0.74"N) Lower Left ( 550500.000, 4270700.000) ( 2d25'12.69"W, 38d35' 0.01"N) Upper Right ( 794100.000, 4507500.000) ( 0d28'44.87"E, 40d39'57.48"N) Lower Right ( 794100.000, 4270700.000) ( 0d22'26.52"E, 38d32'10.04"N) Center ( 672300.000, 4389100.000) ( 0d59'32.03"W, 39d38' 3.63"N) Coordinate System is: PROJCRS["ETRS89 / UTM zone 30N", BASEGEOGCRS["ETRS89", DATUM["European Terrestrial Reference System 1989", ELLIPSOID["GRS 1980",6378137,298.257222101, LENGTHUNIT["metre",1]]], PRIMEM["Greenwich",0, ANGLEUNIT["degree",0.0174532925199433]], ID["EPSG",4258]], CONVERSION["UTM zone 30N", METHOD["Transverse Mercator", ID["EPSG",9807]], PARAMETER["Latitude of natural origin",0, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8801]], PARAMETER["Longitude of natural origin",-3, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8802]], PARAMETER["Scale factor at natural origin",0.9996, SCALEUNIT["unity",1], ID["EPSG",8805]], PARAMETER["False easting",500000, LENGTHUNIT["metre",1], ID["EPSG",8806]], PARAMETER["False northing",0, LENGTHUNIT["metre",1], ID["EPSG",8807]]], CS[Cartesian,2], AXIS["(E)",east, ORDER[1], LENGTHUNIT["metre",1]], AXIS["(N)",north, ORDER[2], LENGTHUNIT["metre",1]], USAGE[ SCOPE["Engineering survey, topographic mapping."], AREA["Europe between 6°W and 0°W: Faroe Islands offshore; Ireland - offshore; Jan Mayen - offshore; Norway including Svalbard - offshore; Spain - onshore and offshore."], BBOX[35.26,-6,80.53,0]], ID["EPSG",25830]] Data axis to CRS axis mapping: 1,2 Origin = (550500.000000000000000,4507500.000000000000000) Pixel Size = (200.000000000000000,-200.000000000000000)

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.
