In 1996, a proposal entitled “Use of Remote Sensing Images to Evaluate and Monitor the Condition of Prehistoric Earthen Structures” was submitted the National Center for Preservation Technology and Training by the Society for American Archaeology.

The intent of the proposed research was to use historic aerial photographs to evaluate the effectiveness of using them as a data source to detect and document change in prehistoric earthen structures through time. There was some reason to believe that photogrammetric methods could serve as a basis for detecting changes in such archaeological remains, since they had apparently been used for such purposes by Blank (1985) at the Hopeton earthworks, part of Hopewell Culture National Historic Park in Ohio.

The research was also to entail the assessment of a number of photointerpretive, photogrammetric, and digital mapping techniques including stereo photointerpretation, digital photogrammetry, digital imaging and image processing, and CAD and GIS technologies in monitoring earthworks and similar cultural resources. The Hopeton earthworks was to be “revisited” using these methods, as well as two other sites at Hopewell Culture NHP. A grant for the research was received from NCPTT later in 1996.
