Noninvasive subsurface mapping techniques, satellite and aerial imagery in landscape archaeology
Authors: Cheetham, P.N.
The future appears bright for the landscape archaeologist as we are entering into a period that will see enormous advances in our understanding of archaeological landscapes. New technologies, some still in their toddler state, if not infancy, will increasingly provide landscape archaeologists with currently unimagined levels of detail regarding human exploitation of landscapes over time. Some survey and mapping techniques such as earthwork surveys and oblique aerial photography, mainstays of archaeology in the 20th century, while still contributing, will take their rightful role as complementary elements in what is becoming GIS-based research spaces dominated and underpinned by geophysical, geochemical, and laser altimetry and hyperspectral imagery data, the last two collected from varying altitudes and platforms. This chapter tries to assess what these technologies are currently contributing to landscape archaeology, as well as their future potential.
