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.     

The Edesö Wreck: the hull of a small,armed ship wrecked in the Stockholm archipelago in the latter half of the 17th century

In 2003 a well‐preserved shipwreck was found north of Dalarö in the Stockholm archipelago. In 2007 and 2008 the site was surveyed jointly by archaeologists from the Swedish National Maritime Museum, Södertörn University and the University of Southampton. The surface finds were inventoried and drawings produced of the hull structure, which measures 20 m between the posts. This paper presents the results of recording the hull. The original name of the ship, as well as the precise history of its demise, are unknown, but it appears to have been a small man‐of‐war, built and probably sunk in the late 17th century. It was possibly built in England, or at least in the English fashion of that time.     

Assembling nostalgia: devices for affective captation on the re:heritage market

This article builds on the current rethinking of nostalgia in heritage studies and an increasing amount of research that explores the formatting of customer – producer relationships in terms of ’market attachments’ to analyse how nostalgia is performative on the market for retro, vintage and second hand, what we call the re:heritage market. Based on a multi-sited study including offline and online ethnographic observations, photography and qualitative interviews with shop owners and staff at a selection of central streets in Gothenburg, Sweden, the article explores the way shop owners work with nostalgia in order to attract, or ‘captate’, the public, through engaging affective market devices. Our particular contribution is to show how the re:heritage market contribute to our understanding of an alternative of cultural heritage, through configuring exchange and value, and details how ‘affective captation’ adds conceptual strength for understanding the emotive and sensate pull of certain market-based heritage practices. Staging nostalgic encounters involves practices of selecting, collecting, displaying and preserving for the future: practices that are vital for all heritage-making. A variety of actors are involved in this unconventional of heritage at safe a distance from traditional heritage practices.     

HOBY — AN EXCEPTIONAL EARLY ROMAN IRON AGE SITE IN THE WESTERN BALTIC REGION

Hoby on the island of Lolland in the western part of the Baltic Sea is strategically located in a coastal landscape offering abundant resources. In 1920, one of the most richly furnished so‐called “Lübsow type” graves dating to the first century AD was discovered at Hoby. The settlement associated with the grave was recognised in 1999. Excavations of the settlement between 2001 and 2016 have confirmed the central role of Hoby in the Iron Age society. The research has focused on the Iron Age population and the infrastructure on Lolland. The Iron Age open cultural landscape encompassed numerous settlements, richly furnished burials and fortifications, and has produced unique metal finds. The article presents a summary of investigation results.     

Cluster evolution and the change of knowledge bases: the development of a design cluster

Most studies portray cluster knowledge bases as a given resource, tied to specific industries and locations. However, this paper challenges that view and uncovers their dynamic nature by identifying endogenous and exogenous triggering events that influence and change the cluster knowledge base mix over time. This is done by building on the theoretical concepts of pre-existing conditions, triggering events and knowledge bases and by drawing on a case study of the design cluster located in the Triangle Area of Denmark. The paper concludes that the design cluster has changed its mix of knowledge bases several times during its evolution. Starting out as a firm-driven cluster with a dominant synthetic knowledge base, it then evolved into an artistic and creative cluster with a prevailing symbolic knowledge base. In the last few years, the cluster has increasingly adopted an analytical knowledge base at the expense of other knowledge bases. These developments have caused numerous changes in both knowledge building and the sources of knowledge in and around the cluster. These findings have implications for the framing of cluster knowledge bases, considering how they emerge, change and combine, as well as how that affects clusters’ composition of actors, activities and resources.

The Power of Models in Planning: The Case of DaisyGIS and Nitrate Leaching

Spatial deterministic simulation models such as DaisyGIS are increasingly being used for decision‐making in European planning. In Denmark specifically, there is an increasing interest at the regional level to use DaisyGIS as an administrative tool. There are, however, uncertainties associated with the use of these deterministic models, partly due to the spatial variation in input parametres. This study evaluates the use of DaisyGIS for nitrate leaching assessments based on nitrate leaching experiments carried out at the Marbjerg experimental site at Roskilde University. The study includes geostatistical analysis of soil and hydraulic variables and the use of remote sensing for deriving spatial information about the Leaf Area Index. It is found that the model predicts nitrate leaching well when using site‐specific input data but it is quite sensitive to the parameterization of carbon, the C/N ratio and variations in the Leaf Area Index (LAI). With the increasing use of Daisy in the counties, there is a need to find better ways of handling uncertainties in model output which can be used by decision‐makers and to study further the impact of spatial LAI assimilation on catchment scale nitrate leaching processes.
