Abstract
The last four decades, worldwide, the landscape rapidly evolved in both a physical and anthropogenic sense. Here, the Nile valley is used as a prime example of how human impact has influenced the physical environment of large river systems. Due to its rich heritage, the cultural and environmental history of the Nile valley has already tremendously been studied. Studies focusing on the cultural history of the Nile valley are mostly field based and pinpointed towards specific target sites. These sites however were implanted in the regional landscape, and as such, information on these sites and their regional landscape are of equal importance. Digital surface models (DSMs), extracted from very high resolution stereoscopic satellite images, are a perfect tool to gain knowledge on this regional landscape aspect. Because of their stereo capability and high spatial resolution of 1.8 m, Corona Stereo couples and thus the derived DSMs are a major source for landscape analysis. In this paper several DSMs created from different Corona stereo couples dating to the early seventies are presented and discussed. The main focus is on the location of the palaeo Nile channels and it’s relation to the surrounding alluvial landscape in the area of Dayr al-Barsha, Middle Egypt. A DSM created from 2009 Worldview-1 stereo images is used as a reference and indicates the current state of the landscape. The combination of the enhanced digital terrain extraction (eATE) module of Erdas Imagine® with ground control points collected in the field and calculated from the 2009 DSM provides accurate DSMs, By comparing the Corona DSMs with the Worldview DSM, it was possible to make a risk assessment of the natural environment and urban development for cultural preservation. This comparison provides information on the complementarities and additive value of different data for archaeological investigation. As a consequence of different missions during the ’70s and frequent coverage of the area of Dayr al-Barsha, different stereo couples were processed. By combining and comparing the generated surface models the representation of the landscape is more accurate as well as the location of the palaeo river beds.
