COSCH Case Studies COSCH Case Studies

Seven case studies implementing 3D spatial and spectral documentation of material cultural heritage were realised in 2015 and 2016. The aim of these case studies is to offer in-depth investigation, enabling a good understanding of selected techniques and processes in 3D spatial and spectral documentation, applied to a particular cultural heritage object or site.

Bremen "Cog"


The Bremen Cog represents one of the founding stone of the German Maritime Museum. The medieval vessel was discovered in 1962 in the River Weser. Since 2000 the ship is on display after: 3 years of excavation, nearly 10 years of documentation and reconstruction, followed by 20 years of conservation.
Although the conservation treatments are completed, it is absolutely necessary to lead further monitoring measurements in order to control regularly the state of the ship. The monitoring must include the environment control in the room, standards in Preventive Conservation (Temperature, Relative Humidity and Light), but also deformation processes. The environmental measurements are already on-going, but the deformation of the wood on the other hand was monitored only occasionally. A systematic and multi-yearly monitoring is currently under active consideration.
A three dimensional monitoring of the Ship would allow the museum's conservator to keep an eye on the ship and wood deformation that occurred in the past and the possible ones to come.
Nevertheless, a closer look at the examples in other museums was necessary, moreover listing the resources used (Equipment, finances and manpower).
A "test phase" was set on maximum 2 years' time comparing 3 methods in order to lead to a long-term solution. The comparison is focusing on the technical issues as well as interpretation possibilities of the data and the costs.

Digital Techniques for Documenting and Preserving Cultural Heritage

"The essays in this collection are transformative, moving beyond basic collaboration and skilfully contextualizing both scientic knowledge in the humanities and humanities knowledge in the sciences. Doing so not only heightens the quality of the research, but heightens understanding, redrawing traditional lines between disciplines and redening what it means to truly collaborate and to be a scholar in the digital age."-Bill Endres, University of Oklahoma 
In this unique collection the authors present a wide range of interdisciplinary methods to study, document, and conserve material cultural heritage. The methods used serve as exemplars of best practice with a wide variety of cultural heritage objects having been recorded, examined, and visualised. The objects range in date, scale, materials, and state of preservation and so pose dierent research questions and challenges for digitization, conservation, and ontological representation of knowledge. Heritage science and specialist digital technologies are presented in a way approachable by non-scientists, while a separate technical section provides details of methods and techniques, alongside examples of notable applications of spatial and spectral documentation of material cultural heritage, with selected literature and identication of future research. 
This book is an outcome of interdisciplinary research and debates conducted by the participants of the COST Action TD1201, Colour and Space in Cultural Heritage, 2012–16, and is an Open Access publication available under a CC BY-NC-ND licence.
