Investigating the Potential of Infrared Remote Sensing in Archaeological Survey

Cody Dobson, Dr. Connie Arzigian, Department of Archaeology and Anthropology, University of Wisconsin-La Crosse 435A Wimberly Hall, 1701 Farwell St, La Crosse, WI 54601

Archaeological walking survey continues its prominent use in data collection and public outreach to this very day.  Although it is continuously used, limitations arise due to its reliance on participants’ physical ability and their prowess for seeing and recognizing archaeological remains.  Unmanned aerial vehicle remote sensing, commonly known as drone photography, has the ability to maintain the practice of volunteers while expanding site identification accuracy, range, and efficiency.  In creating spectral curves, which show an object’s reflectance of light at different light wavelengths, for fire-cracked dolomite, we attempt to find a common semi-homogeneous archeological remain that can be used to identify it through unmanned aerial vehicle remote sensing.  If these curves are statistically different from dolomite, fire-cracked dolomite may very well be a means of identifying archaeological sites in the Midwest and beyond.  The underlying objective is to develop a 95% confidence interval for the wavelengths of diagnostic light absorption of fire-cracked dolomite.  The definition of these wavelengths offers surveyors wavelengths they can then use to image and identify fire-cracked dolomite in a laboratory setting.  Potential future research could then be carried out both in a professional and undergraduate setting to test these finds in the field with known archaeological sites featuring fire-cracked dolomite.  With these intervals established, analysis will look to determine if the wavelengths of light absorption are statistically different from dolomite signatures obtained from other research.  No research has been found comparing the reflective signatures of fire-cracked rocks and minerals to their unbaked counter parts. Statistically different signatures would allow surveyors features useable in the identification of sites more likely marked by human manipulation of fire, instead of displaced dolomite.
