Ryan-Harley: Visualizing the Suwannee Surface

This project was a continuation of the work I started while I was at Texas A&M University. I worked with Ph.D. candidate Morgan Smith to map the spatial distribution of artifacts found at the Ryan-Harley site which is located along the Wacissa river in northern Florida.

The maps below represent the Suwannee Surface which is a stratigraphic layer located as little as 52cm below the modern surface. The stratigraphy for the entire island was recorded by use of auger coring with each auger's location measured using GPS. From each core, the beginning of the Suwannee surface was identified and measured in centimeters from the modern surface. Measurements were recorded and tied to their corresponding GPS points to create a geodatabase which was used in ArcGIS to create both 2D and 3D representations of the surface. The raster below was interpolated with an Ordinary Kriging method which used an exponential semivariogram model.
