Remote sensing: Aerial photography and satellite imagery

Abstract

As noted in the introduction, the site was fi rst detected in early summer 2001 during the aerial archaeology research school through aerial survey exercise. In the following years we did not have the opportunity to survey the site from the air because of logistical problems until the spring of 2004 (Campana et al. 2006). In that year, from the end of May to the middle of June, throughout the crop-ripening season, the site was repeatedly monitored from the air to record the aerial visibility of the cropmarks, using fl ights at intervals of between two and four days to document their development. This procedure allowed the clear identifi cation of new traces that had not been visible when the site was fi rst discovered in 2001 (Fig. 1). Photography was also continued into the later months of the summer. The new evidence included traces of an abandoned river-course and two new structures in the north-western part of the fi eld, adjacent to the main complex of buildings.
