This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Satellite and aerial images are used for archaeological site prospection worldwide. However, manually detecting and mapping archaeological sites from imagery can be time consuming. This poster examines the utility of an image processing and unsupervised classification procedure for archaeological feature detection and mapping in arid settings. This...
Geospatial Analysis of Areal (Polygonal) Units: Applications at the Site Level (2015)
Currently, and for the first time in the age of GIS, there is a growing resurgence of interest in intra-site level spatial analysis. Many studies focusing on the application of GIS technology to site level phenomena focus, either explicitly or implicitly, on the analysis of fine resolution datasets. Realistically, however, few archaeological data are recorded as sub-centimeter points. The majority of archaeological data tends to be recorded at the resolution of the 1x1 or 2x2 meter excavation...
Hilltop Visibility Networks and Empire in the Moche Valley (2016)
Prehistorically used in contexts ranging from mountain deity veneration to imperial conquest and warfare, hilltops serve as excellent platforms for staying connected to and informed of the surrounding social, political, and ritual landscape. This being said, how can the characteristics of visibility networks between hilltop sites help inform archaeologists of the ancient socio-political and ritual settings on which they were situated? Featuring dozens of hilltop sites that temporally correlate...
Investigating a Late Holocene Subsistence Transition North of the Alaska Range: Compelling Results from Two Archaeological Sites (2017)
Geospatial analyses on dated sites across central Alaska suggest important subsistence changes occurred in the region between 4000-2000 years ago. A significant shift from a general foraging strategy to a targeted collecting strategy appears to have occurred during this time, and recent investigations at two archaeological sites dating to this period have begun to shed light on the timing and extent of this subsistence shift in a specific region of central Alaska.
Modeling the formation of lithic surface assemblages through the application of aerial photography and photogrammetry (2016)
Previous research has demonstrated that surface artifacts provide insight into land-use patterns when the taphonomic processes influencing their distribution are understood. This understanding is derived from detailed field mapping of landscape topography and geomorphology. Aerial imagery, when combined with photogrammetry and geospatial analysis, produces datasets that can be used to characterize the erosional processes that actively influence the occurrence of surface material. Using unmanned...
Playing with Fire at ‘Ais Giorkis: A Geospatial Analysis of Prehistoric Fire Residue (2015)
Kritou Marottou Ais Giorkis is an Early Neolithic (9.5 kya) site located, uniquely, in the western foothills of Cyprus’ Troodos Mountains. It is one of five near contemporary sites and has produced the largest chipped stone and faunal assemblages recovered thus far. There are also several preserved circular, cobbled platforms, whose function has yet to be determined. In fact, little is currently understood about the lifeways practiced at the site. This includes the intensity and duration of its...
