Geographic Visualization in Archaeology

Archaeologists are often considered frontrunners in employing spatial approaches within the social sciences and humanities, including geospatial technologies such as geographic information systems (GIS) that are now routinely used in archaeology. Since the late 1980s, GIS has mainly been used to support data collection and management as well as spatial analysis and modeling. While fruitful, these efforts have arguably neglected the potential contribution of advanced visualization methods to the generation of broader archaeological knowledge. This paper reviews the use of GIS in archaeology from a geographic visualization (geovisual) perspective and examines how these methods can broaden the scope of archaeological research in an era of more user-friendly cyber-infrastructures. Like most computational databases, GIS do not easily support temporal data. This limitation is particularly problematic in archaeology because processes and events are best understood in space and time. To deal with such shortcomings in existing tools, archaeologists often end up having to reduce the diversity and complexity of archaeological phenomena. Recent developments in geographic visualization begin to address some of these issues, and are pertinent in the globalized world as archaeologists amass vast new bodies of geo-referenced information and work towards integrating them with traditional archaeological data. Greater effort in developing geovisualization and geovisual analytics appropriate for archaeological data can create opportunities to visualize, navigate and assess different sources of information within the larger archaeological community, thus enhancing possibilities for collaborative research and new forms of critical inquiry.

LAPMv2 - software for underwater large-area photo-mosaicking

LAPMv2 is a research software solution specifically developed to allow marine scientists to produce geo-referenced visual maps of the seafloor, known as mosaics, from a set of underwater images and navigation data. LAPMv2 has a graphical user interface that guides the user through the different steps of the mosaicking workflow. LAPMv2 runs on 64-bit Windows, MacOS X and Linux operating systems. There are two versions for each operating system: (1) the WEB-installers (lightweight but require an internet connection during the installation) and (2) the MCR installers (large files but can be installed on computer without internet-connection). The user manual explains how to install and start the program on the different operating systems. Go to http://www.lapm.eu.com for further information about the latest versions of LAPMv2.

An archaeology of female monasticism in medieval Ireland

This thesis considers the archaeological evidence for female monasticism in medieval Ireland, with a particular emphasis on the later medieval period. Female monasticism has been considered from an archaeological perspective in several countries, most notably Britain, but has yet to be considered in any detail in Ireland. The study aims to bring together all the currently available evidence on female monasticism and consider it through an engendered archaeological approach. The data gathering for this research has been deliberately wide, and where gaps have been identified in the Irish evidence, comparative material from elsewhere has been considered. Nunneries should not be expected to conform to what has become the male monastic template of a claustrally-planned monastery. The research conducted shows a distinct and varied archaeology and architecture for medieval nunneries in Ireland which suggests that a claustral plan was not considered an essential part of a nunnery scheme. Nunneries provided an enclosed environment where women, for a variety of motives could become brides of Christ. Through the performance and celebration of the daily Divine Office, the Mass and seasonal liturgy, spaces used by the nunnery community were negotiated and transformed into a sacred Paradise on earth. However, rather than being isolated in the landscape nunneries in later medieval Ireland were located either within or close to walled towns, larger unenclosed settlements and settlement clusters and would have been well known throughout their hinterlands. This research concludes that nunneries were an intrinsic part of the medieval monastic landscape in Ireland and an essential component of patrons’ portfolios of patronage, at a particularly local level, and where they interacted closely with their local community.

Telephones, Voice Recorders, Microphones, Phonographs: A Media Archaeology of Sonic Technologies in Twin Peaks

This article argues that sonic technologies, such as telephones, voice recorders and phonographs, alongside more (audio)visual ones such as flickering fluorescent lights, videos, and the television sets are crucial to the world of Twin Peaks, and constitute this world as both a communications network with portals to the unknown, and an accumulation of recordings of ghosted voices and entities, perhaps finding its ultimate expression in the backwards reprocessed speech in the Black Lodge. This lodge can be understood as a space in which there are nothing but recordings, albeit now on a cosmic, spiritual and demonic level. Using a media archaeological approach to these devices in the series, this paper will argue that they were already operating by a media archaeological logic, generating the world of Twin Peaks as a haunted archive of sonic and other mediations.

Breaking Open the Black Boxes: media archaeology, anarchaeology and media materiality

An essay on the emergent methodology of media archaeology, in realtion to the material turn in approaches to digital media. In particular, this article advocates taking up Siegfried Zielinski's concept of 'anarchaeology', but in a different sense to the way it was originally proposed, in order to emphasise the political potentials of a media (an)archaeological methodological approach.

Towards an Archaeology of Media Ecologies: The Case of Italian Free Radios

This article looks at the contemporary reinvention of the term Media Ecologies in the work of Matthew Fuller, arguing that its provenance is less form Postman's Media Ecology Association andmore form the work of Felix Guattari. It then presents an account of free radios in Italy and France in the 1970s and contemporary pirate radio as exemplary cases of media ecologies in Fuller's sense of the term

What is this thing called Historical Archaeology?

Historical archaeology, in its narrow temporal sense -as an archaeology of the emergence and subsequent evolution of the Modern world- is steadily taking pace in Spanish academia. This paper aims at provoking a more robust debate through understanding how Spanish historical archaeology is placed in the international scene and some of its more relevant particularities. In so doing, the paper also stresses the strong links that have united historical and prehistorical archaeology since its inception, both in relation to the ontological, epistemological and methodological definition of the first as to the influence of socio-political issues in the latter. Such reflection is partly a situated reflection from prehistory as one of the paper’s authors has been a prehistorian for most of her professional life.

Negative Archaeology. The Archaeological Borders of the Present

Nowadays, archaeology is trying to redefine its relation with objects. This change is taking place at the same time as the West is breaking once and for all with the generation who did the rural exodus in the mid of the twentieth century. The present paper proposes a revision of the conditions that allow us to both define this rupture and at the same time determine our affinity with materiality. This is done through a reconsideration of the relation between the past and the present and the dynamics marking this difference. We are situated in a moment when the experience of time is shifting and thus so is the integrity of archaeological objects. Under the name of Negative Archaeology, the border between past and present is explored. This border determines the creation of the past in a present which intends to homogenise changes. Archaeology is a unique discipline which could prevent this process, or at least bear witness to the dynamics to which objects seem to be subjected. Obscolescence is introduced as a concept in an attempt to name the aforementioned problem.

Archaeology, Architecture and Digital Adaptation: Developing a GIS for Archaeological Excavation on Crete

This paper is not about the history or archaeology of Priniatikos Pyrgos per se. Rather, it is a review of how the site was recorded using both traditional survey and planning techniques and digital approaches applied through a Geographical Information System (hereafter GIS) during the 2007 through 2010 seasons. Earlier work at the site will necessarily be reviewed, specifically the geophysical survey work of the Istron Geoarchaeological Project and the excavations by Hayden and Tsipopoulou between 2005 and 2006, and regional survey work by Hayden and colleagues in the Vrokastro region (Hayden, this volume, 1999, 2004; Sarris et al. 2005; Shahrukh et al. 2012). The digitisation and incorporation of the latter into the project GIS will be explored in some detail.

Using augmented state Kalman filter to localize multi autonomous underwater vehicles

The present paper describes a system for the construction of visual maps ("mosaics") and motion estimation for a set of AUVs (Autonomous Underwater Vehicles). Robots are equipped with down-looking camera which is used to estimate their motion with respect to the seafloor and built an online mosaic. As the mosaic increases in size, a systematic bias is introduced in its alignment, resulting in an erroneous output. The theoretical concepts associated with the use of an Augmented State Kalman Filter (ASKF) were applied to optimally estimate both visual map and the fleet position.
