  1. Presented by Harold Frank October 20, 2009 Using a GIS to Model PrehistoricSite Distributions in the UpperChesapeake BayKONNIE L. WESCOTT AND JAMES A. KUIPER

  2. 39,000 acres • Predictive Modeling of an old military site • Aberdeen Proving Ground • Model based on associated data • Primarily because of unexploded military ordnance Model designed around distance To examine possibility of finding shell middens Upper Chesapeake Bay

  3. Project Area

  4. Developed by Argonne National Laboratory Predictive Modeling for all Federal facilities Goal – manage all Federal facilities in a cost efficient manner Model would consider air & water quality, wetlands, T & E species and cultural resources 100 data layers gathered To date only 1% has been surveyed for cultural resources Aberdeen (Maryland) Proving Grounds Model

  5. Time and money to do a controlled survey with field verification special consideration Safety consideration over unexploded ordnances were the overriding concern As a result, 572 prehistoric sites in other areas of Upper Chesapeake Bay used instead Examined for shell midden and non-shell midden site Proximal distance to water ended up being the overarching parameter Limitations of Aberdeen Model

  6. Figure 4.2 – Distance to Water

  7. Figure 4.5 – Elevation from DEM

  8. Results of Predictive Model

  9. Figure 4.8 Non-shell Predictive Model

  10. Figure 4.9 Combined Predictive Model

  11. Figure 4.10 Combined Predictive Model with known sites

  12. Safety First when walking through unexploded ordnances Use other data when bombs present Directs and channels planners to reduce sites to potential areas to examine (i.e. predictive model) Intensive archeology still necessary Conclusion
