This study focuses on the Altamira Cave’s karst system in Spain, resulting in a thorough 3D mapping encompassing both cave interior and exterior topography along with significant discontinuities and karst features in the vicinity. Crucially, GPR mapping confirms that primary vertical discontinuities extend from the near-surface (Upper Layer) to the base of the Polychrome layer housing prehistoric paintings. This discovery signifies direct interconnections helping with fluid exchange between the cave’s interior and exterior, a groundbreaking revelation. Such fluid movement has profound implications for site conservation. The utilization of various GPR antennas corroborates the initial hypothesis regarding fluid exchanges and provides co...

Methodological issues concerning the role of archaeological imaging are often implied within those debates. Do the tracings belong to the observational data exposition chapter, or are they part of the interpretative conclusions? How can the current technological scenario help solve these problems? In 2017, we conducted new documentation of the Peña Tu rock shelter, a well-known site with an intriguing post-palaeolithic graphic collection documented on several occasions throughout the 20th century. Our objective was to provide quantifiable and, if possible, objective documentation of the painted and engraved remnants on the shelter's surface. To achieve this, we employed two data capture strategies. One strategy focused on analyzing the vestiges of paintings using a hyperspectral sensor, while the other centred on the geometric d...

As it is notably fragile, it is fortunate that some instances remain intact—but a variety of natural and anthropogenic factors can lead to its disappearance. Therefore, as a valuable cultural heritage, rock art requires special conservation and protection measures. Geomatic remote-sensing technologies such as 3D terrestrial laser scanning (3DTLS), drone flight, and ground-penetrating radar (GPR) allow us to generate exhaustive documentation of caves and their environment in 2D, 2.5D, and 3D. However, only its combined use with 3D geographic information systems (GIS) lets us generate new cave maps with details such as overlying layer thickness, sinkholes, fractures, joints, and detachments that also more precisely reveal interior–exterior interconnections and gaseous exchange; i.e., the state of senescence of the karst that houses the cave. Inf...

During this time, we have examined not only each and every one of the figures discovered by him, but have also expanded the list, reaching nearly all the 450 new figures in the entire cave. This significant increase is thanks to the use of new technologies, such as a 3D scanner, digital filters, multispectral algorithms, giga images, or the newest innovation, the use, for the first time in our studies on cave art, of hyperspectral methodology. The latter gives us access to a much wider light spectrum than the one created by multispectral analysis.

La labor de reconocimiento llevada a cabo en los últimos años ha permitido extender las evidencias a zonas hasta ahora vacías y ha puesto sobre la mesa importantes datos para afrontar en el futuro una interpretación de conjunto del fenómeno. Uno de los nuevos conjuntos recientemente descubiertos se localiza también en la zona de Ojos Albos, a poca distancia de Peña Mingubela, aunque los motivos pictóricos de esta última estación se referencian en épocas sin duda más recientes. La intención de este estudio es dar a conocer el conjunto de pintura rupestre de La Peña del Castrejón, localizado en una pared que no llega a constituir un abrigo propiamente dicho, muy expuesta, en la que se apreciaba a simple vista un antropomorfo con piernas y brazos en arco. ...

Our Palaeolithic ancestors did not make good representations of themselves on the rocky surfaces ... more Our Palaeolithic ancestors did not make good representations of themselves on the rocky surfaces of caves and barring certain exceptions – such as the case of La Marche (found on small slabs of stone or plaquettes) or the Cueva de Ambrosio – the few known examples can only be referred to as anthropomorphs. As such, only hand stencils give us a real picture of the people who came before us. Hand stencils and imprints provide us with a large amount of information that allows us to approach not only their physical appearance but also to infer less tangible details, such as the preferential use of one hand over the other (i.e., handedness). Both new and/or mature technologies as well as digital processing of images, computers with the ability to process very high resolution images, and a more extensive knowledge of the Palaeolithic figures all help us to analyse thoroughly the hands in El Castillo cave. The interdisciplinary study presented here contributes many novel developments based...

It was made by making incisions and/or applying natural pigments mixed with water or organic elements on a rock surface, which for millennia has been subjected to different factors of natural and anthropogenic alteration that have caused its deterioration and/or disappearance. The present paper shows a methodology that employs hyperspectral technology in the range of visible light and the near infrared spectrum, providing a scientific and non-destructive way to study, conserve and manage such a valuable cultural heritage. Recognition of coloring matter, formal recognition of the figures, superposition of forms and documentation of the state of conservation are relevant topics in rock art, and hyperspectral imaging technology is an efficient way to study them. The aim is to establish a method of creating pigment cartography and enhancing the visualization of rock art panels. Illumination s...

El trabajo da a conocer el hallazgo de estructuras arquitectónicas que conforman un entramado urbanístico. Las ruinas afectadas se asocian a materiales de irrefutable cronología romana. La caracterización del enclave se ha realizado desde una actuación multidisciplinar, en la que los datos arqueológicos han sido asistidos por prospección geofísica; así como, labores de extracción y consolidación de restos de pintura mural. Las evidencias constatadas indicaron la existencia de un edificio noble o de función pública, posiblemente asociado a estancias calefactas o sauna: hallazgo de téselas de mosaico, pilae, opus signinum, estucos. A tenor de un fragmento de terra sigillata con inscripción latina (primera manifestación de escritura en la cuenca baja del Besaya), o el conocido denario de Augusto, se sostiene que se trata de una población de elevada romanización. Se maneja una cronología no contrastada enmarcada en los primeros siglos de nuestra era. Un análisis de arqueología espacial, sugiere la vinculación de este enclave arqueológico con un puerto marítimo.
Construction works in the vicinity of the parish church of the coastal town of Suances (Cantabria) uncovered new evidence of a Roman settlement. In situ investigation revealed architectural structures that clearly imply the existence of an urban framework. The ruins damaged by the construction work are associated with archaeological materials of undeniable Roman chronology. A multidisciplinary approach, combining geophysical survey tools (georadar prospection) and the removal and consolidation of mural paintings in order to support archaeological data, was applied to characterize the site. Verified evidences suggest the existence of a noble or public building, possibly linked to heating or sauna facilities: mosaic tiles, pilae, opus signinum and stucco were discovered. On the basis of a terra-sigillata fragment with a Latin inscription (first evidence of writing in the lower Besaya River basin), and a well-known Augustus denarius also found in the site, we argue that this
was a highly Romanized settlement. The settlement is considered to date back to the early first centuries AD (chronology to be confirmed). An archaeological landscape analysis suggests the site is linked to a maritime port.

Measurements from 3D Terrestrial Laser Scanner come in a point cloud, and different types of surfaces such as spheres or planes can be modelled. Due to the occlusions and/or limited field of view, it is seldom possible to survey a complete feature from one location, and information has to be acquired from multiple points of view and later co-registered and geo-referenced to obtain a consistent coordinate system. The aim of this paper is not to match point clouds, but to show a methodology to adjust, following the traditional topo-geodetic methods, 3DTLS data by modelling references such as calibrated spheres and checker-boards to generate a 3D trilateration network from them to derive accuracy and reliability measurements and post-adjustment statistical analysis. The method tries to find the function that best fits the m...

This sum of applications has been used with great success in the famous panel of the Hands of El Castillo. Possibly this panel has been one of the most studied by all researchers who have preceded us in the analysis of this cavity from the Abbe H.
Breuil until today. Some of them have made small contributions, reviewing some of the defining figures of animals or in more detail some of the negative hands that
had already identified the famous French researcher.
