“…For example, laser scanning has recently been used to examine the effects of different storage environments on the morphology of wet-preserved wooden objects from archaeological sites (Lobb et al, 2010). The fact that diachronic changes to these wooden objects were identified and detected at sub-millimeter levels of accuracy suggests that conservators could monitor the deterioration of exterior wooden surfaces at Fort Conger using high-resolution scanners like the Minolta 910 Vivid.…”

ABSTRACT. Fort Conger, located in Quttinirpaaq National Park, Ellesmere Island, is a historic landmark of national and international significance. The site is associated with many important Arctic expeditions, including the ill-fated Lady Franklin Bay Expedition of the First International Polar Year and Robert Peary's attempts to claim the North Pole. Although situated in one of the most remote locations on earth, Fort Conger is currently at risk because of the effects of climate change, weather, wildlife, and human activity. In this paper, we show how 3D laser scanning was used to record cultural features rapidly and accurately despite the harsh conditions present at the site. We discuss how the future impacts of natural processes and human activities can be managed using 3D scanning data as a baseline, how conservation and restoration work can be planned from the resulting models, and how 3D models created from laser scanning data can be used to excite public interest in cultural stewardship and Arctic history.Key words: laser scanning, heritage preservation, Arctic exploration, inorganic contamination, virtual reality, computer modeling RÉSUMÉ. Fort Conger, situé dans le parc national Quttinirpaaq, sur l'île d'Ellesmere, est un lieu historique d'importance nationale et internationale. Ce site est lié à de nombreuses expéditions arctiques importantes, dont l'infortunée expédition de la baie Lady Franklin relevant de la première année polaire internationale et les tentatives de revendication du pôle Nord par Robert Peary. Bien qu'il se trouve dans l'un des endroits les plus éloignés du globe, Fort Conger subit actuellement les risques découlant des effets du changement climatique, des conditions météorologiques, de la faune et de l'activité humaine. Dans cette communication, nous montrons comment un scanneur laser 3D a permis de répertorier les caractéristiques culturelles avec rapidité et précision malgré les conditions difficiles qui ont cours à ce site. Nous discutons de la manière dont les incidences futures des processus naturels et de l'activité humaine peuvent être gérées à l'aide des données 3D comme données de base, comment les travaux de conservation et de restauration peuvent être planifiés à partir des modèles qui en résultent et comment les modèles 3D créés à partir des données de scannage laser peuvent rehausser l'intérêt du grand public à l'égard de la gérance culturelle et de l'histoire de l'Arctique.Mots clés : scannage laser, préservation du patrimoine, exploration de l'Arctique, contamination inorganique, réalité virtuelle, modélisation informatisée Traduit pour la revue Arctic par Nicole Giguère.

“…Due to the wide spreading of the high-resolution laser scanning survey instruments, the computer-based three-dimensional (3D) investigations of the hand tool impressions could be arranged without any difficulty. After a similar data collection, the comparison of the wooden finds and their tool marks was achieved in digital environment within a more recent archaeological project (Lobb et al 2010). The visual evaluation of the tool marks and their signatures means a common method during the evidence investigation in the field of forensic science just like in the tool mark identification case of a mattock to a clod of soil (Clark 2011).…”

ABSTRACT:The acquisition of high-resolution surface information by advanced documentation methods as short-range laser scanning or closerange photogrammetry can provide novel tool mark research perspectives in the field of archaeological sciences. For this reason, altogether eight different Bronze Age hand tool replicas and their tool marks were surveyed and analysed in this study. The automatic identification of sliding tool marks was carried out in a GIS environment. Based on hydrological and aspect parameters, the various hand tool impressions as watershed boundaries of the surface model could be determined in the developed workflow. After the segmentation of the single tool marks, slope and width values of the patterns were compared with the cutting edges of their replicas and the most used regions of the hand tool heads could be defined by these tool mark characteristics. The variation of midline parameters along the sliding tool marks resulted in significant conclusions about the mounting techniques of the hand tool heads on the handles. A smaller angular value between the replica and the handle produced different hand tool impressions which had a major influence on the woodworking efficiency as well. Furthermore, in this paper presented methods should also help to understand other ancient wood manufacture processes.

“…These objects were stored in various conditions and the deformation differences were investigated after these preservation processes. The three-dimensional (3D) analysis of the tool marks on these finds was accomplished by surface comparison in digital environment (Lobb et al 2010). The analysis of cut marks on bones was carried out in another significant archaeological research project, which has provided a workflow to classify the various cut marks by statistical methods (Domínguez-Rodrigo et al 2012).…”

ABSTRACT:The improvement of detailed surface documentation methods provides unique tool mark-study opportunities in the field of archaeological researches. One of these data collection techniques is short-range laser scanning, which creates a digital copy of the object's morphological characteristics from high-resolution datasets. The aim of our work was the accurate documentation of a Bronze Age sluice box from Mitterberg, Austria with a spatial resolution of 0.2 mm. Furthermore, the investigation of the entirely preserved tool marks on the surface of this archaeological find was also accomplished by these datasets. The methodology of this tool mark-study can be summarized in the following way: At first, a local hydrologic analysis has been applied to separate the various patterns of tools on the finds' surface. As a result, the XYZ coordinates of the special points, which represent the edge lines of the sliding tool marks, were calculated by buffer operations in a GIS environment. During the second part of the workflow, these edge points were utilized to manually clip the triangle meshes of these patterns in reverse engineering software. Finally, circle features were generated and analysed to determine the different sections along these sliding tool marks. In conclusion, the movement of the hand tool could be reproduced by the spatial analysis of the created features, since the horizontal and vertical position of the defined circle centre points indicated the various phases of the movements. This research shows an exact workflow to determine the fine morphological structures on the surface of the archaeological find.
