This subsurface can help possibly pinpoint the exact location of the plantation house. Radar uses EM waves to determine the shape of objects based on the reflectivity of the object being imaged.
iii) <u>Resistivity:</u>
The resistivity of the ash bed will be different from the resistivity of the material used to build the house, and this difference in resistivity can be used in a resistivity survey to locate the house.
