La necrópolis del Monte de Santa Mariña revisitada: aportaciones del LIDAR aéreo para la cartografía megalítica de Galicia

Abstract: ResumenEl Lidar aéreo se ha constituido en la última década como una de las herramientas más interesantes para la prospección arqueológica, puesto que permite, entre otras cosas, analizar el terreno con gran detalle obviando la vegetación. Planteamos un ejemplo de las posibilidades que para el Megalitismo la tecnología Lidar puede proporcionar. Para ello, hemos elegido la necrópolis megalítica del Monte de Santa Mariña (provincia de Lugo, Galicia), que cuenta con una treintena de monumentos catalogados. Para e… Show more

“…From the resulting model, a two-folded line of study is obtained. On the one hand, a Digital Elevation Model (DEM) is generated to study the microtopographies of the stone with geographic analysis techniques provided by Geographic Information Systems (GIS) from different lighting conditions and surface reflections, which are calculated by hillshading or LRM (Local Relief Model) for the interpretation of the object (Carrero-Pazos, Vilas, Romaní, & Rodríguez, 2014;Gawior, Rutkiewicz, Malik & Wistuba, 2017). On the other hand, from both the 3D model and the point cloud, the study is completed with the application of the methods of analysis and visualisation based on the Morphological Residue Model (MRM) which stands out every single detail of the surface morphology of the object (Caninas, Pires, Henriques, & Chambino, 2016;Correia, Pires, & Sousa, 2014).…”

“…Las líneas de investigación con estas herramientas se centran en la creación de un MDE, generado a partir de los datos LiDAR o fotogramétricos, sobre el que se desarrollan e implementan métodos de visualización generando archivos 2D con la imagen resultado. Las técnicas más extendidas en los análisis SIG son los llamados hillshade, sky-view factor, slopeshade y LRM (Carrero-Pazos, Vilas, Romaní, & Rodríguez, 2014;Gawior, Rutkiewicz, Malik & Wistuba, 2017). Estudios recientes aplican estás técnicas comparando los resultados a partir de datos LiDAR de distinta resolución (1 m o 5 m), con datos fotogramétricos, concluyendo que la fotogrametría de alta resolución mejora los resultados de los datos LiDAR (Fernández-Lozano & Gutiérrez-Alonso, 2016).…”

“…Although this method has been used in research for over a decade, most case studies have concentrated in northern Europe (Bewley et al, ), owing to the lack of LiDAR in the south of Europe. However, data has been available for Spain since 2015, and this has allowed a reappraisal of some megalithic territories (Carrero‐Pazos, Vilas Estévez, Romaní Romaní, & Rodríguez Casal, ; Cerrillo‐Cuenca, ), but this is not the case of Portugal. The systematic application of photo‐interpretation is very recent and has been focused mainly on ditched enclosures (Jiménez‐Jáimez, ; Valera & Pereiro, ).…”

“…LiDAR is especially recommended for the study of non-built-up, extra-urban areas where traces of buried archaeological sites can be effectively recovered. In recent years, a large number of fortified enclosures and prehistoric megalithic structures [8,9], Roman camps [10][11][12][13][14] and Roman constructions [15] have been detected in extra-urban areas of Spain through LiDAR-PNOA acquisitions.…”
