Typological Classification and the Chronology of Iron Age pottery in central-southern Britain

Pottery has been one of the most popular artefacts in the study of the Iron Age in central-southern Britain because of its advantages of commonality, durability and volume. Pottery studies have provided important clues for understanding the society and culture in the region. These studies also have contributed to constructing the chronologies of the regions. However, pottery studies have tended to be unpopular in recent decades. Despite their crucial importance to the field of Iron Age archaeology, ceramic studies of classification and chronology have not been adequately developed. The lack of these places all related studies at a disadvantage, which can be clearly identified in recent works of the region. This thesis re-examines the existing fundamental studies of Iron Age pottery. The method of classification and chronology of pottery uses statistical analyses, considering the importance of objectivity and actual data, which appears to be lacking in the existing studies. According to this approach, a new framework of the Iron Age pottery is created. The analysis also addresses other important issues for ceramic studies including classification, stratigraphy and absolute dating. These issues are discussed in order to produce reliable studies in the future by providing useful approaches to ceramic chronology. Most importantly, this thesis aims to emphasise the importance of the classification and chronology of pottery and to encourage the continuous re-examination of these studies

Geoarchaeological Approaches to Pictish Settlement Sites: Assessing Heritage at Risk

Due to the poor preservation of Pictish period buildings and the occupation deposits within them, very little is known of daily life in early medieval Scotland. In lowland and coastal areas, Pictish buildings are generally truncated by deep ploughing, coastal erosion, or urban development, while those uncovered in upland areas seem to have no preserved floor deposits for reasons that remain poorly understood. Geoarchaeological techniques are particularly effective in clarifying site formation processes and understanding post-depositional transformations. They are also a powerful research tool for identifying floor deposits, distinguishing their composition, and linking this to daily activities. However, archaeologists are often reluctant to apply geoarchaeological methods if they suspect preservation is poor or stratigraphy is not visible in the field. This study therefore employs an innovative suite of geoarchaeological techniques to evaluate the preservation of Pictish period buildings and the potential that fragmentary buildings have to reconstruct daily life in early medieval Scotland. Alongside literature analysis and a desk-based comparison with national soil datasets, over 400 sediment samples from three key settlement sites were subjected to integrated soil micromorphology, x-ray fluorescence, magnetic susceptibility, loss-on-ignition, pH, electrical conductivity and microrefuse analysis. The combined data were successful in generating new information about the depositional and post-depositional history of the sites, preservation conditions of the occupation deposits, and activity areas within domestic dwellings. Most significantly, the integrated approach demonstrated that ephemeral and fragmented occupation surfaces retain surviving characteristics of the use of space, even if floors are not preserved well enough to be clearly defined in the field or in thin-section. A partnership with Historic Environment Scotland has channelled this work into research-led guidelines aimed at communicating geoarchaeological methods and principles to a wider audience

High scale 3D modelling and orthophoto of curved masonries for a multipurpose representation, analysis and assessment

It is important nowadays to underline some relevant topics concerning the effective contribution of 3D high detailed products derived from innovation and integration of Geomatics technologies, allowing a remarkable development in descriptive metric capabilities, supporting and improving the material recording, representation, analysis and characterization about alteration of the constructive systems. Considering the relevance of the complex interdisciplinary research of these issues that move around the Cultural Heritage safeguard and due to its extreme vulnerability, these models must give a response to different problems. Primarily they has to provide complete models on which to pursue accurate morpho-dimensional documentation, and to base structural assessment, decay investigations, and consequently to underpin restoration practices and support operational workflow in CH assets monitoring. Some peculiarities of new methods for semi-automatic processing algorithms are thus evidenced, advantaging their proficiency to behave as tools for a more sustainable approach in the general process of preservation and protection. Specifically about the ancient masonries documentation, the chance of using digital products derived from very high scale models, as the detailed orthoimages projection and surfaces development offers many opportunities. Here, a late-medieval stratified dovecote tower in Verolengo (TO) with a particular trunk-conical shape had been analysed in order to reconstruct an identity and a historical and architectural framework, de facto not recognized yet. A 3D reconstruction by dense matching techniques will be presented, in the complex context that are the vertical high buildings, presenting one of the highest level of vulnerability. The importance of the 3D model availability, closely connected to dense radiometric information, has been particularly expressed in two main direction for the diagnosis both of volumetric structure assessment and the material characterization of the mixed masonries walls

UAV PHOTOGRAMMETRY WITH OBLIQUE IMAGES: FIRST ANALYSIS ON DATA ACQUISITION AND PROCESSING

In recent years, many studies revealed the advantages of using airborne oblique images for obtaining improved 3D city models (e.g. including façades and building footprints). Expensive airborne cameras, installed on traditional aerial platforms, usually acquired the data. The purpose of this paper is to evaluate the possibility of acquire and use oblique images for the 3D reconstruction of a historical building, obtained by UAV (Unmanned Aerial Vehicle) and traditional COTS (Commercial Off-the-Shelf) digital cameras (more compact and lighter than generally used devices), for the realization of high-level-of-detail architectural survey. The critical issues of the acquisitions from a common UAV (flight planning strategies, ground control points, check points distribution and measurement, etc.) are described. Another important considered aspect was the evaluation of the possibility to use such systems as low cost methods for obtaining complete information from an aerial point of view in case of emergency problems or, as in the present paper, in the cultural heritage application field. The data processing was realized using SfM-based approach for point cloud generation: different dense image-matching algorithms implemented in some commercial and open source software were tested. The achieved results are analysed and the discrepancies from some reference LiDAR data are computed for a final evaluation. The system was tested on the S. Maria Chapel, a part of the Novalesa Abbey (Italy)

The Form and Abandonment of the City of Kuik-Mardan, Otrar Oasis, Kazakhstan in the Early Islamic Period

A joint Kazakh-British archaeological initiative undertook a survey and excavation of the city of Kuik-Mardan, one of the largest of the seventy or so known settlements in the Otrar oasis on the Syr-Darya river, Kazakhstan. Several complimentary field techniques were employed including unmanned aerial vehicle photomapping and an extensive programme of radiometric dating. The radiocarbon dates obtained are the first for any city in the oasis and allow more confident interpretations of the experience of the city to be ventured. Also undertaken was a geoarchaeological investigation of the surrounding irrigation and water supply canal system. Key results include its wholesale destruction during the 6th to 7th century and the form of the later occupation of the city

Fotogrametría UAV en apoyo del levantamiento de un sitio arqueológico. modelos 3D en la Hierápolis de Frigia (Turquía)

[EN] Unmanned aerial vehicle (UAV) photogrammetry has shown a very rapid development in many fields, especially in archaeological excavation areas and architectural complexes, where it offers a detailed generation of three-dimensional (3D) data including the possibility of updating over time. It also proves to be a very flexible tool applicable to many types of complex areas with a variety of different features. The use of aerial acquisition provides highly effective results, adding to both rapid capture and lower costs. In fact, today in the field of archaeological research, great efforts are invested in the generation of very large-scale models and orthophotos, and the technology seems to promise further future developments, not only from the terrestrial (orthogonal) point of view, but also from the nadiral direction from a low altitude, as a preferential and often optimal point of view. Here an effective workflow for photogrammetric product generation is presented for selected case studies in some monumental areas of ancient Hierapolis in Phrygia (Turkey), in which the Italian Archaeological Mission of Hierapolis (MAIER) has been working since the 1960s. The recent experiences achieved by UAV photogrammetry are quite innovative. The variety and complexity of the buildings, as well as the height of their ruins, offer numerous challenges, which are interesting to deal with. The 3D aerial survey was performed for multiple purposes with the eBee system by Sensefly. Specific attention was paid to the digital surface model (DSM) and aerial orthoimages of three test areas: the Plutonium area; the Thermal Bath-Church; and the Necropolis. Starting from the same technical approach, a comparative assesment among the three sites was carried out, taking into account the specific goals, the type of the structure and the terrain conformation.[ES] La fotogrametría con vehículos aéresos no tripulados (Unmanned Aerial vehicle, UAV) ha mostrado un desarrollo muy rápido en muchos campos, especialmente en áreas de excavación arqueológica y complejos arquitectónicos, donde ofrece una detallada generación de datos tridimensionales (3D), junto con su actualización en el tiempo. También demuestra ser una herramienta muy flexible aplicable en muchos tipos de áreas complejas, con diferentes características formales. El uso de la toma aérea proporciona hoy resultados altamente efectivos, lo que aumenta la rapidez de adquisición y menores costes. De hecho, hoy en día en el campo de la investigación arqueológica, se invierten grandes esfuerzos a la hora de generar modelos y ortoimágenes a grandes escalas, y parece prometer más desarrollos futuros, no sólo desde el punto de vista terrestre (ortogonal), sino también con dirección nadiral, desde baja altitud, como punto de vista preferencial y óptimo. Aquí se presenta un flujo de trabajo eficaz que permite generar productos fotogramétricos en varios casos de estudio en áreas monumentales de la antigua Hierápolis de Frigia (Turquía), donde la Misión Arqueológica Italiana de Hierápolis (MAIER) ha estado funcionando desde los años 1960. Estas experiencias logradas con la fotogrametría UAV son bastante innovadoras. La variedad y la complejidad de los edificios, así como la altura de sus ruinas ofrecen numerosos puntos problemáticos que son interesantes de tratar. El levantamiento aéreo 3D se realizó con múltiples propósitos por medio del sistema eBee de Sensefly. Se prestó especial atención al Modelo Digital de Superficie (MDS) y a las ortoimágenes aéreas en tres áreas de prueba: el área de Plutonio; la Iglesia-Baño Termal; y la Necrópolis. Partiendo del mismo enfoque técnico, se ofreció una evaluación comparativa de los tres sitios, teniendo en cuenta los objetivos específicos, el tipo de estructura y la configuración del terreno.Chiabrando, F.; D'andria, F.; Sammartano, G.; Spanò, A.

Archaeological signatures of landscape and settlement change on the Isle of Harris

Between 2004 and 2011, a programme of archaeological investigation by the University of Birmingham on the Isle of Harris, a distinctive island forming part of the Western Isles of Scotland, has allowed the archaeological remains of this enigmatic place to be further characterised and understood. Despite intensive archaeological interest in the archipelago for a number of decades, the Isle of Harris has been overlooked and only now are we beginning to identify the archaeological resource and make comparisons to the wealth of published data from islands such as the Uists, Barra and Lewis. This paper highlights some generic overall patterns of archaeological signatures on the Isle which has been identified through a range of archaeological methods including field walking, intrusive excavation, aerial reconnaissance, geophysical and topographical survey, and documentary research. Several key case studies will be introduced including upland shieling complexes and mulitperiod settlement sites on the west coast machair systems. The purpose of the paper is not to present a gazetteer of the results of the work to date, but to highlight some of the key findings with a view to demonstrating that the Isle of Harris is directly comparable with the archaeologically rich landscapes of the other islands
