This paper tackles principal component analysis (PCA) in images that include wavelengths between 380-1000 nm. Our approach is focussed on taking advantage of the potencial of ultraviolet and infrarred images, in combination with the visible ones, to improve documentation process and rock art analysis. In this way, we want to improve the discrimination between pigment and support rock, and analyse the spectral behaviour of rock art paintings in the ultraviolet and infrared regions. Three images were used, one image from the ultraviolet (UV) region, one from the visible region (VIS) and another one from the near infrared region (NIR). Optical filters coupled to the camera optics were used to take the images. These filters capture specific wavelengths excluding radiation that we are not interested in registering. Finally, PCA is applied to the acquired images. The results obtained demonstrate the PCA usefulness with imagery in this field and also it is possible to extract some conclusions about the correspondent paint pigments.http://dx.doi.org/10.4995/CIGeo2017.2017.6597

Situs Kel Lein di Pulau Kaimear, Kepulauan Kei, adalah salah satu situs gambar cadas yang baru ditemukan. Situs ini dilaporkan pada 2018 dan dilanjutkan dengan perekaman data intensif pada tahun berikutnya. Berbagai motif seni cadas yang tersebar di sepanjang teras, dinding, dan atap ceruk gua dibagi menjadi tujuh panel. Pendekatan dalam penelitian ini menggunakan deskriptif kualitatif. Data yang dikumpulkan dari survei lapangan pada tahun 2018, ditambah data terbaru yang diperoleh pada tahun 2019. Analisis gambar cadas dibagi menjadi beberapa panel di dalam ceruk, terdiri dari tujuh panel. Penelitian ini mencatat 488 motif, yang dikelompokkan menjadi motif figur manusia atau antropomorfik, perahu, alat batu, cap tangan (negatif), jejak kaki, geometris, lingkaran, garis vertikal dan horizontal, wajah atau topeng manusia, ayam atau hewan, tempayan (tembikar), jaring ikan, matahari, bulan, dan panah. Penelitian ini menunjukkan bahwa banyak motif gambar cadas di Situs Kel Lein mengandung berbagai makna. Salah satunya adalah aktivitas manusia yang digambarkan dalam bentuk figuratif. Keragaman motif di Situs Kel Lein menempatkan situs ini pada posisi penting dalam kajian jalur migrasi manusia. Diperkirakan situs ini adalah salah satu lokasi yang cukup ramai disinggahi pada masa lalu. The Kel Lein Site in Kaimear Island, Kei Islands, is a recently discovered rock art site. This site was reported in 2018 and continued with intensive data recording the following year. Various rock art motifs scattered along the terrace, walls, and roof of the niche are divided into seven panels. The approach in this research uses descriptive qualitative. The data collected from a field survey in 2018, plus the latest data obtained in 2019. The rock art analysis is divided into several panels inside the niche, comprising seven panels. This research recorded 488 motifs, grouped into human or anthropomorphic figure, boats, stone tools, hand stencils (negative), footprints, geometric, circles, vertical and horizontal lines, human faces or masks, chickens, jars (pottery), fishing nets, sun, moon, and arrowheads. This research shows that many rock art motifs on the Kel Lein Site show various purposes. One of which is human activity depicted in a figurative form. The diversity of motifs at the Kel Lein Site places this site in a vital position in studying human migration pathways. It is estimated that this site is one of the most visited posts in the past.

We present a case study on digitalization of Southern Rock Art (“Arte Sureño”) in a prehistoric rock shelter from Los Barrios, Cádiz (southern Iberian Peninsula); there we use SfM techniques to obtain some digital products for both analytic and divulgation goals. This way, we highlight some opportunities that low-cost devices (e.g. no-professional digital camera) and open software have introduced in archaeology today. We made it to converge in a working process to register and manage rock art expressions and their immediate surroundings (i.e. natural stone blocks, walls, niches…). From this action, we not only support our work in digital 3D about multiple and varied entities that make up the scenario and neighbour context of rock art through the use of multiple low cost / free resources, but also, we intend to adjust all this operative for the processes of investigation, protection and diffusion on the varied cases that make up this unique singular artistic heritage.http://dx.doi.org/10.4995/CIGeo2017.2017.6658

Petrified Forest

Located in northeastern Arizona (USA), Petrified Forest National Park (PEFO) presents a unique story of both geologic and human history. Though perhaps most well-known for its abundant petrified wood and being part of the Painted Desert, visitors are often surprised when they discover PEFO hosts many ancient petroglyph sites. Over the years, many attempts have been made to record the petroglyph sites, but nothing has been done to assess their geomorphic stability. To address this shortcoming, we employed the Rock Art Stability Index (RASI) to assess geologic stability and (potential) deterioration of rock art sites in PEFO. Used for more than a decade as a triage for researchers assessing which rock art panels/sites are in the most danger of eroding, RASI uses a rank-based system to assess over three-dozen rock decay parameters, resulting in an overall condition analysis of a rock art panel. The findings can then be grouped together by site location to gain a clearer understanding of overall decay processes responsible for (potential) erosion. This study highlights RASI, its use as a low-cost, non-invasive, rapid field assessment technique, and assesses the geomorphic stability of five major petroglyph sites in the Petrified Forest National Park.

Rock art analysis has been used both to provide insight into prehistoric symbolism and ceremony, and to measure prehistoric interaction and communication. But chronological control, essential to distinguishing functional or social differences from temporal differences, has been difficult to establish. No one method of dating has yet proven completely reliable or applicable. Accelerator mass spectrometer radiocarbon dating, at the Tom Ketchum Cave pictograph site in southeastern Arizona, provides one of the first examples of direct independent dating of rock art. The dates suggest the pictographs may have been created during a time when subsistence patterns were shifting from Archaic hunter and gatherer traditions to more agriculture-based subsistence. The Tom Ketchum Cave artists broke from the abstract style more common in the region to represent game animals and hunters, perhaps to ensure success in a disappearing way of life.

RESUMEN Este trabajo de investigación aborda uno de los objetos de estudio más singulares del patrimonio arqueológico: el arte rupestre. Por lo que hace a su ámbito territorial, se circunscribe al suroeste de la provincia de Ciudad Real: Montes de Ciudad Real, Valle de Alcudia y Sierra Madrona. Desde el punto de vista teórico-metodológico, esta investigación se encuadra dentro de la denominada arqueología del paisaje. Este enfoque condiciona las técnicas de registro y documentación de las entidades a estudiar. Por esta razón, el eje temático de este trabajo está fundamentalmente constituido por una aproximación a las técnicas y métodos de registro más apropiados para la catalogación e interpretación de las representaciones rupestres: Sistemas de Información Geográfica (SIG), fotogrametría, láser escáner y análisis de imagen. En virtud de su bajo coste, facilidad de manipulación y rentabilidad de cara a la explotación de los datos, se han seleccionado varias de estas herramientas para su aplicación en el estudio de caso propuesto: el sitio rupestre de Puerto Baterno (Agudo, Ciudad Real). Se ha realizado, así, un análisis de este yacimiento inédito a diferentes escalas espaciales: paisaje, entorno y estación.   PALABRAS CLAVE: arte rupestre, arqueología del paisaje, SIG, fotogrametría, análisis de imagen   ABSTRACT This research aims to study one of the most unique items of archaeological heritage: rock art. Its scope is limited to the southwest of the province of Ciudad Real: Montes de Ciudad Real, Valle de Alcudia and Sierra Madrona. From the theoretical and methodological point of view, this research is located in the orbit of the so-called landscape archeology. This approach determines the recording and documentation techniques of the artistic expressions studied. For this reason, the central theme of this work will be mainly composed of an approach to the most appropriate recording techniques and methods for its cataloging and interpretation: GIS, photogrammetry, laser scanning and image analysis. Due to its low cost, ease of manipulation and the profitability of the exploitation of data, we have selected several of these tools for its use in the study of this proposed case: the rock art site of Puerto Baterno (Agudo, Ciudad Real). We have done an analysis of this unknown site on different spatial scales: landscape, environment and station.   KEY WORDS: rock art, landscape archaeology, GIS, photogrammetry, image analysis

Art Analysis

This chapter explores questions of ontology in rock art analysis. More specifically, it argues that the distinction between ‘informed’ methods and ‘formal’ methods reproduces some problematic dichotomies, such as the distinction between active subjects and inert objects, culture and nature, and a conceptualization of meaning as being external to the art itself. The chapter proposes a move away from such an ontologically hierarchical approach to rock art analysis to a relational approach in which there is no ontological priority between the different elements that make up the rock art assemblage. It emphasizes that placing formal methods at the heart of rock art studies, alongside analogy, shifts the questions we ask of rock art away from simple epistemologically derived enquiries to ontological questions. To illustrate this the chapter examines case studies of parietal art of the European Palaeolithic and Comanche rock art in North America.
