Advanced remote sensing technologies were used to generate elevation data from high-resolution satellite stereo-imagery of the Ikonos sensor for the generation of accurate topographic maps. Additional very high-resolution imagery of the WorldView-2 sensor was used to produce orthorectified image maps that facilitate local site management. Terrestrial measurements from previous field surveys were used for image geo-referencing and validation of the DEM from the stereo-imagery. Elevation points were derived in a semi-automatic process and adjusted by stereo-inspection through a human operator. Contour lines and shaded relief maps are created in the next step to be combined with findings from previous archaeological surveys. The superposition of all available information indicates that the existing boundaries of the World Heritage property and buffer zone are to be adjusted. The resulting maps serve as a planning base for future development activities, such as the enforcement of the river embankment to protect the minaret from flooding. The analytical data also serve for future numerical studies of the flooding regime at this particular place. It is argued that all data and cartographic products are required in such complicated cases with access restrictions for intensive fieldwork and should be considered in similar cases by researchers and planners. All activities form part of the international efforts to establish a protection scheme supporting the longterm management and the preservation of the World Heritage property.

Today inhabited, the island was the site of the world’s earliest maritime sanctuary (ca. 2750-2300 BC). Recent excavations are highlighting the remarkable monumentality of the proto-urban settlement adjacent to the sanctuary, which shows precocious evidence for metalworking and agricultural intensification. The comprehensive paper-free digital recording strategy (to be described in full elsewhere) includes an iPad-based recording system (iDig) used in the field and in the laboratory, producing a single excavation database. Spatially, individual contexts are recorded using photogrammetry. Additionally, each excavation trench is 3D documented by means of a terrestrial laser – scanner. The latter aspect of the work is reported in detail here. Eine korrigierter Nachdruck kann unter https://dx.doi.org/10.15496/publikation-94856 aufgerufen werden.

This paper addresses the advantages as well as the difficulties in using retrospective photogrammetry and examines how the results can be put to use for further research, preservation, restoration, monitoring rates of deterioration and presentation to the public. We examine the approach to retrospective photogrammetry from the perspective of both the photogrammetrist and the end user (ie. researcher, scholar or authority responsible for using or disseminating the resulting data). From the perspective of the photogrammetrist it is the nature and quality of the archival data that is of concern. Does the archival material meet the needs of 3D modeling and will the resulting models meet the needs of the end user? The end user is concerned with being able to store, access and utilize the results constructively. An impressive 3D model without detail or metrics is of little use apart from public presentation. We explain why the end user’s goals must be addressed clearly prior to commencing the project. We will look at examples from the Athenian Agora and Ancient Corinth to illustrate the methods required, limitations experienced and opportunities made possible with the resulting products. 2.

This paper discusses the benefits of extracting information embedded in aerial photogrammetric images and using them to improve mapping and documentation of archaeological sites. This paper offers three case studies to provide examples of how aerial photogrammetric imagery can help identify features and patterns not always recognizable from the ground or from standard aerial images.
