Remote Sensing and GIS at Guilford Courthouse National Military Park (GUCO) The Sequel! {hope you saw Jacob Turner’s Award winning paper yesterday}

2013 North Carolina Geographic Information Systems Conference Roy Stine UNCG

Project Goals

• To use multiple methods of remote sensing; including a Ground Penetrating Radar (GPR) and a dual flux gate gradiometer , to help place excavation units and facilitate data recovery.

• Help locate the original Guilford Courthouse and possibly the third Continental Line.

• Education: for both the students and the general public.

Project Notes • Methods of remote sensing; including a Ground

Penetrating Radar (GPR) and a dual fluxgate gradiometer and aerial photographs.

• Metal detecting 3,800 square meters, Magnetometer 4,605 square meters, GPR 2,714 square meters

• Over 120 anomalies recorded and mapped

• Six 2x2 m units were excavated, one 4x.5 m trench and eleven 50x50 cm shovel tests

• Approximately 10,000 artifacts are being washed, catalogued, preserved and analyzed

March 15th 1781 General Greene and ~ 4,400 American Militia and Regulars General Cornwallis and ~ 1,900 British Greene use tactics that Morgan used at Cowpens

Help Locate the Courthouse and the Third Battle Line

Conclusion

• We did not conclusively find the Guilford County Courthouse.

• We did have great success with helping the archaeologist locate excavation units.

• We located the old excavations of Coe and Ward.

• We located at least three unknown structures and possibly two addition structures.

• We located either the “Retreat Road” or the Gully; both pivotal in the 3ed line actions.

Where to Next? Raster is faster but vector is corrector – or is it?

Combining the data, statistical, image processing and GIS analysis

• Graphic overlay, photo-interpretation

• Binary maps

• Boolean logic (intersection – union)

• Principal Components – Factor Analysis

• Classification

Thank you – Questions?

• Really we have time for questions

• This is the last session

• On the last day and

• This is the last paper

• You’re next chance will not come until 2015

• Hey we can go to a bar and discuss it… • Besides if the UNCG lawyer will not sign a standard EULA for my software

(one which all the other UNC system lawyers have signed) I’ll be fired, and have to live under a bridge

• I’ll hang out on a street corner with a sign “will image process for food”

• Anyone want hire a softwareless remote sensor GIS type guy?

• Will work for software?

• Will image process for greyhound kibbles
