Airborne multispectral and hyperspectral remote sensing techniques in archaeology : a comparative study
Traditional and well-established applications of airborne remote sensing to archaeology involve standard aerial photographic recording, either oblique or vertical, of archaeological phenomena visible as shadow, soil or cropmarks, all of which require particular conditions before they become visible. Cropmarks have made the most important contribution to archaeological site discovery and are the most complex of the phenomena, whose occurrence relies upon the differential availability of moisture to a crop growing over buried archaeological remains, reflecting different soil depths and precipitation, to create differential growth patterns in times of moisture stress. Consistently successful aerial photographic reconnaissance for cropmarks relies on dry weather and well-drained soils in arable agriculture. There is, thus, in Scotland a bias in the discovery of archaeological sites in favour of drier eastern districts, supporting arable agriculture, compared to the west with its wetter climate focussed on pastureland. Because cropmarks are linked to moisture stress in growing plants they are potentially detectable in bands outside the visible part of the electro-magnetic spectrum. Although historically cropmark
