On-Site Recording of Excavation Data Using Mobile GIS

Abstract

Archaeologists have embraced new technologies in many aspects of research, but reliance on paperbased recording has impeded development of excavation recording methods. The digital recording of spatial provenience for artifacts and features, together with complex attributes during excavation, while not problem-free, provides a streamlined recording process. This article describes a digital interface that links precise spatial provenience with digital forms and geo-referenced photographs during excavation at a colonial site in highland Peru. A customized version of ESRI ArcPad provides the means to create and to explore spatial and attribute data in the field and laboratory as GIS data, which in turn can be integrated with ArcGIS for post-field visualization and analysis.     

Community Collaboration and Other Good Intentions

Collaborative and community-based archaeological research encompasses a broad spectrum of approaches; however, there are often discrepancies between how researchers ‘sell’ the collaborative endeavour in theory and how it is actually practised. Over the past several years, I have had the opportunity to participate in several projects, ranging from those that claimed to be ‘truly collaborative,’ to research that maybe should have asked, ‘what community?’ These experiences raised difficult and disturbing questions concerning the nature and practice of collaborative and community-based archaeology. In this paper, I confront these issues as I have experienced them personally. While community-based practices aim to redress a historical and ongoing power imbalance between the researcher and the researched, constant vigilance is required lest the ‘good intentions’ of anthropologists inadvertently mask an exploitation that may be inherent in the structure of research itself. In considering the corporate nature of academia, I query whether the collaborative research model represents a break with the past, or is instead simply the same old practice dressed up in fashionable new language.     

Managing Long Distance and Localized Learning in the Emilia Romagna Life Science Cluster

The paper provides some empirical evidence of the effectiveness of the “open innovation” model in the life science cluster of Emilia Romagna (a region of Italy), comparing the network of R&D collaborative activities in public research organizations (PROs) and the network linked to R&D collaborative activities in private firms. By presenting the main results of a field research in the life science sector in Emilia Romagna, we are contributing to the recent debate focused on the crises of the old “closed innovation” model and the rise of the “open innovation” model. Our survey consists of both primary data deriving from face-to-face interviews with researchers and entrepreneurs, and secondary data extracted from the Internet, the PubMed database, and from the European Patent Office. Our work is based on the analysis of a representative sample of 30 research groups in PROs, 2173 scientific articles published by the interviewed scientists, and a representative sample of 78 private firms.

Collections,Collecting and Collectives: Gathering Heritage Data with Communities in the Mountains of Matatiele and Lesotho,Southern Africa

Gathering digital data is a twenty-first-century research concern. Working in the previously undocumented region of the Eastern Cape’s former 'Transkei' homeland presents several data collection opportunities and obstacles. Local community collectives can vastly enhance the data collection process, aiding in administration, field walking, translation and—as trained archaeologists—excavation and rock art documentation. In the last 7 years, the Matatiele Archaeology Rock Art (MARA) team has discovered over 240 archaeological sites, the vast majority of which contain rock art. The principal investigator (PI), postdoctoral fellows, technical skills specialists and students have all engaged with, helped train and benefitted from field technicians chosen by the local communities to work with us. With their help, we have undertaken excavations and taken thousands of documentary photographs. We have documented oral traditions and the indigenous knowledge of local healers, all of which research is produced, and stored, digitally and requires preservation in perpetuity. The present contribution outlines some of the many and varied ways in which this programme has undertaken these tasks, in the endeavour to redress the imbalance in this region’s history.     

When Natural met Social: A Review of Collaboration between the Natural and Social Sciences

Abstract

This paper investigates the opportunities for further collaboration between the natural and social sciences. From 81 systematically identified and reviewed papers published in scientific journals, it became clear that complex situations that depend on human behaviour as well as natural processes require natural–social science collaboration. The creation of a community of collaborative natural–social science research, that learns from and can contribute to best practice across the sciences, is advocated to support natural– social science collaboration. Across disciplines, it became clear that such a community should deal with (1) difference between paradigms in the current sciences; (2) creation of skills and competences of the involved scientists; (3) scarcity of institutions sympathetic to collaborative research; and (4) the internal organization of collaborative projects.     

New Fathoms in Scientific Exploration: The DeepWrecks Project

Modern technology lends itself to holistic exploration and widely accessible outreach. New technology allows scientists studying our planet either from space or deep under the seas, to explore and reveal both natural and cultural resources that have previously escaped our scrutiny. However, the use of these new technologies is expensive and often the exclusive tool of industrial research. Yet, these new technologies can lead the way to greater collaboration, better science and more public access. In 2003 and 2004, a landmark project, combining government agencies, industrial technology and outreach set new standards in collaborative scientific exploration. The project focused on six shipwrecks at depth in the Gulf of Mexico. The questions posed by the project illuminate how science and industry can collaborate to produce remarkable results. The papers presented in this issue form a model for deepwater exploration.     

Community Archaeology in Proto-Historical Tel Bareqet,Israel: School Children and Agency for Active Public Engagement in Cultural Heritage Projects

Abstract

Community archaeology has become very popular over the past decade, and community archaeology projects are yielding interesting results in many regions around the globe (Merriman, 2004). These projects seem to be gaining academic importance as well, and are considered by some people to be vital to the survival of archaeology as a whole (Marshall, 2002: 218).

Still, community archaeology projects often stir debate regarding their importance, role, and existence. A major theme of these discussions is the role played by the community. In particular, the question is often raised of what role, if any, should be given to non-professional local populations in a project's scientific decision-making.

The current article aims to present the controversy between two types of archaeological practices, 'archaeology from above' and 'archaeology from below' (Faulkner, 2000) through the examination of a community archaeological project in which schoolchildren constitute the community participants. The site of the excavation is Tel Bareqet, a 5000-year-old (Early Bronze Age II, c. 3050–2700 BCE) urban settlement located in central Israel. On the one hand, the excavation strives to maintain the highest scientific standard; on the other hand, it depends upon the participation of unskilled young people in the excavation process.

This article presents obstacles that have been encountered in this excavation, and describes the methodological framework that has been developed in order to overcome these obstacles and continue carrying out a successful community archaeology project.     

3D heritage visualisation and the negotiation of authenticity: the ACCORD project*

This article examines the question of authenticity in relation to 3D visualisation of historic objects and monuments. Much of the literature locates their authenticity in the accuracy of the data and/or the realism of the resulting models. Yet critics argue that 3D visualisations undermine the experience of authenticity, disrupting people’s access to the materiality, biography and aura of their historic counterparts. The ACCORD project takes questions of authenticity and 3D visualisation into a new arena – that of community heritage practice – and uses rapid ethnographic methods to examine whether and how such visualisations acquire authenticity. The results demonstrate that subtle forms of migration and borrowing occur between the original and the digital, creating new forms of authenticity associated with the digital object. Likewise, the creation of digital models mediates the authenticity and status of their original counterparts through the networks of relations in which they are embedded. The current pre-occupation with the binary question of whether 3D digital models are authentic or not obscures the wider work that such objects do in respect to the cultural politics of ownership, attachment, place-making and regeneration. The article both advances theoretical debates and has important implications for heritage visualisation practice.

Semantically Enhanced 3D: A Web-based Platform for Spatial Integration of Excavation Documentation at Alken Enge,Denmark

ABSTRACT

The photorealistic and geometrically accurate 3-dimensional representation of excavations, provided by image-based modeling, has the potential to transform the process of excavation documentation, making it easier to share observations with other researchers. Paradoxically, however, spatial representation lacks the ability to convey archaeological interpretations. By example of excavations in Alken Enge, Denmark, this paper explores how a web-based 3D platform is able to facilitate the collaborative exchange of 3D excavation content and how the integration of spatial and attribute data into one common event-based data model may be advantageous. This includes enhancing the semantic value of field-recorded 3D models by segmenting the geometry using various techniques, such as 3D projections and machine learning. Accordingly, the paper demonstrates a framework for interactive 3D models, which includes attributed classification based on segmented 3D content correlated with traditional raster, vector, and textual data, delivering a spatially integrated platform for collaborative research.     

Standardisation in 3D Geometric Morphometrics: Ethics,Ownership, and Methods

The collection and analysis of 3D digital data is a rapidly growing field in archaeology, anthropology, and forensics. Even though the 3D scanning of human remains in archaeology has been conducted for over 10 years, it is still frequently considered as a new field. Despite this, the availability of 3D scanning equipment and the number of studies employing these methods are increasing rapidly, and it is arguably damaging to the validity of this field to continue to consider these methods new and therefore not subject to the same standardisations as other researches. This paper considers the current issues regarding the lack of standardisation in the methods, ethics, and ownership of 3D digital data with a focus on human remains research. The aim of this paper is to stimulate further research and discussion, allowing this field to develop, improving the quality and value of future research.     

Site Interiography and Geophysical Scanning: Interpreting the Texture and Form of Archaeological Deposits with Ground-Penetrating Radar

The remarkable potential of geophysical scanning—to assess the internal variability of sites in new ways, to highlight important phenomena in the field, to exercise co-creation of interpretation and commitment to minimal destruction of community partners’ resources, and to aid in the practice of due diligence in avoiding desecration of the sacred—continues to be underutilized in archaeology. While archaeological artifacts, features, and strata remain primary foci of archaeological geophysics, these phenomena are perceived quite differently in scans than in visual or tactile exposures. In turn, new registers of site exploration afforded by geophysical prospection may be constrained by the language of site excavation and visual observation, requiring adjustments in the ways of thinking about and describing what the instruments are measuring. The texture and form of site deposits as rendered in ground-penetrating radar scans can be examined in detail prior to making interpretations of cultural features or stratigraphy. Far more than simple “anomalies” demanding our attention for excavation, patterns in geophysical data can be the focus of extensive archaeological analysis prior to, in conjunction with, or independent from excavation.     

The 4th-century B.C. shipwreck at Mazotos,Cyprus: New techniques and methodologies in the 3D mapping of shipwreck excavations

Abstract

Well preserved ancient shipwrecks are rare in the archaeological record, but when discovered, they can provide valuable information on a wide range of research issues if analyzed and documented properly. In this paper we discuss the significance, potential, and constraints of mapping methods applied during the underwater excavation of shipwreck sites with special emphasis on stratigraphy, documentation of finds, and reconstruction of site formation processes. As a case study, we present the digital photogrammetry and computer vision software programs used in the excavation of the 4th-century b.c. shipwreck at Mazotos, Cyprus. Our goal is to develop a targeted documentation and mapping method of ongoing shipwreck excavations so that others can address complex research questions concerning this unique discipline of archaeology.     

Recent archaeological research at Saruq al‐Hadid,Dubai, UAE

In September 2014, the University of New England (UNE), Australia, began a three‐year programme of archaeological fieldwork and post‐excavation analyses focused on the site of Saruq al‐Hadid. In this paper, we present the initial results of our current field and laboratory research particularly related to site stratigraphy and formation processes, relative and absolute chronology, and the preliminary results of various programmes of post‐excavation analyses including archaeobotanical, zooarchaeological, ceramic and archaeometallurgical studies. These studies provide new data to build into the archaeological understanding of Saruq al‐Hadid that has, to date, focused largely on intensive excavation.     

Turbo Island,Bristol: excavating a contemporary homeless place

This paper provides an assessment of the excavation of an apparently ordinary space in Bristol (UK) in 2009. Although the space appears unremarkable to most passers-by, it is unusual in being a place used routinely by many of the city’s street-drinking and homeless community. Homeless people were ‘colleagues’, involved in excavation, finds processing and interpretation. The collaborative nature of this project goes further than merely attempting to represent social groups who have traditionally been excluded from heritage practice and interpretation — it lays methodological foundations for praxis.

Processing Complexity in Networks: A Study of Informal Collaboration and its Effect on Organizational Success

Do organizations with more collaborative partners perform better than organizations with fewer partners? And is this relationship conditional on the ability of those partners to provide nonredundant resources from their network of contact with other actors? This article answers these questions with data describing the participation of governmental and nongovernmental organizations in the Cooperative Funding Initiative (CFI), a program sponsored by the one of the five water management districts in Florida. Results show a positive relationship between the inclusion of more partners in a project and the chances of getting funded, but also that once the project becomes too inclusive; those chances decrease if the partners fill more structural holes (e.g., provide more nonredundant resources). In other words, organizations perform better by adding more partners as long as this addition does not result in excessive complexity. These results are valuable for the growing community of policy scholars seeking to understand the specific conditions under which collaborative behavior positively affects organizational performance.     

Towards a three-dimensional cost-effective registration of the archaeological heritage

Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage.
