Papers by Martin Fera
Im Rahmen eines zweijährigen Projektes konnte nach einer Pilotphase das Leithagebirge, ein etwa 200 km2 großes, zusammenhängendes Waldgebiet, gescannt werden. Das resultierende Geländemodell mit 0,5 m Auflösung zeigt noch nie dagewesene Einblicke in eine historisch über mehrere Jahrtausende gewachsene Kulturlandschaft mit Fluren, Be-stattungsplätzen, Siedlungsräumen, Befestigungen, Wege-netzen und industriellen Anlagen. Somit konnte sich ALS bei der Auffindung von archäologischen Fundplätzen unter Vegetation bewähren und wird sich in naher Zukunft als archäologische Prospektionsmethode etablieren können.
Abandoned meander belts, as an example, reveal possible tectonic tilting towards the Southeast in the Southern Vienna Basin and a paleochannel migration towards the same direction. The constantly changing river channels and linked flood hazards in the floodplains has always been an important determining factor for the selection of settlement areas. Archaeological sites, for instance, are mainly located on the rim of the Würmian terraces, at the margin of the subrecent floodplain.
Summary: This paper presents a GIS-based system, that was developed and used at a project investigating settlement and funeral areas in Sudan. The 3-dimensional documentation of a pharaonic town and associated funeral area, founded and used during the New Kingdom in Nubia, required a robust and adaptable system to deal with various feature types and scales in challenging environmental settings. The system based on a Totalstation, Image-based Modelling and a Geodatabase enabled the researchers to enhance the geometric accuracy of the documentation and speed up the process to gain more field time for descriptive and interpretative tasks.
For a few years, these algorithms are embedded in several free and low-cost software packages. This paper will outline how such a program can be applied to map archaeological excavations in a very fast and uncomplicated way, using imagery shot with a standard compact digital camera (even if the images were not taken for this purpose). Archived data from previous excavations of VIAS-University of Vienna has been chosen and the derived digital surface models and orthophotos have been examined for their usefulness for archaeological applications. The absolute georeferencing of the resulting surface models was performed with the manual identification of fourteen control points. In order to express the positional accuracy of the generated 3D surface models, the NSSDA guidelines were applied. Simultaneously acquired terrestrial laser scanning data – which had been processed in our standard workflow – was used to independently check the results. The vertical accuracy of the surface models generated by SfM was found to be within 0.04 m at the 95 % confidence interval, whereas several visual assessments proved a very high horizontal positional accuracy as well.

The main objective of the symposium is to offer a multidisciplinary forum to discuss relevant topics and specific issues in cultural heritage protection and management and the application of digital methods for this purpose. The program shall encourage the scientific exchange and strengthen collaborative ties between participating institutions as well as increase the awareness of non-invasive methods in cultural heritage protection among stakeholders and the interested public.
Session 3: Raising Awareness for digital methods for cultural property protection and cultural heritage management
Within the framework of the project, a strategy has been adopted by the partners from 10 countries of the Danube region. The strategy approaches the topic of archaeological heritage from an archaeological, social and a technological standpoint. By using SWOT (Strengths, Weaknesses, Opportunities, and Threats) analyses conducted by the
working groups, major challenges in the sector were defined, leading to two main strategy units. The first unit focuses on working processes from the archaeological discovery to a virtual visualisation, and the second on the potential of archaeological heritage in the digital world. To support the
further adaptation and development of new technologies for the archaeological sector, the strategy concludes with 12 recommendations for heritage stakeholders. Priority lists are adopted for the implementation of the recommendations at national level for each participating country.
