A View From Afar:
The Use of Remote Sensing
Technologies to Examine Hopewell
Sites in Ohio
Capstone Presentation:
American Anthropological Association
111th Annual Conference
San Francisco, California
November 14-18, 2012
Timeline of Mound Building Cultures in Ohio
Adena: 800 BC to 100 BC
Hopewell: 200 BC to 500 AD
Fort Ancient Tradition (Mississippian): 1000 AD to 1500
Mound Destruction
The Need for
Preservation
Study Areas and Major Rivers of Ohio
Resources Used in this Study
1. Early maps of Hopewell mounds and earthworks retrieved from: Squier, E. G., & Davis, E. H. (1848). Ancient Monuments of the Mississippi Valley (Classics in
Smithsonian Anthropology). Smithsonian Books.
2. Modern orthorectified aerial photography (Tiff Format) and Lidar data (las. format) available from the State of Ohio Office of Information Technology (2011), Ohio
Geographically Referenced Information Program.
3. ODOT (Ohio Department of Transportation) shapefiles for Airport, Active Rail, City, County, Interstate, State Routes, Township, and US Routes.
4. DNR (Department of Natural Resources) hydrography shapefile of Ohio‘s water sources, and divide line between Lake Erie and the Ohio River.
5. USGS (United States Geological Survey) aerial photographs from the late 1950's and 1960's, as well as SRTM DEMs.

View of Seip Earthworks Facing Southwest, Elevation TIN using MARS
The Elevation has been Multiplied by Seven to Illustrate the Earthworks & Mound Remains
Seip Site Facing Northwest, Using Quick Terrain Modeler
The Elevation Has Been Reduced to Between 698 and 711 Feet to Illustrate the Remains of the Earthworks
