Hampton Hills: The Search for Buried Archaeology

Electrical Resistivity Data

Several sequences of processing steps were applied to the raw data for both the resistivity and magnetometry data.  Prior to identifying the optimal processing steps for this particular data, many trial sequences were applied in GeoPlot.  Listed below are the final processing sequences completed on the resivitity data to optimize the low contrast features.   

Processing Sequences

1. Clip
2. Edge Matching
3.   Despike
4.   Zero Mean Traverse
5.   High Pass Filter
6.   Color Palette

Below is an image of the final processed electrical resistivity data.

 

Magnetometry Data

A similar sequence of trial and error processing was applied to the unprocessed gradiometer data.  Below we have listed the final sequence of processing steps. 

Processing Sequences

The final processed gradiometry data is shown here. 

 

INTERPRETATION

We interpret the data to be representative of a possible historical feature, such as drainage ditches.  This is evidenced in the data by the long linear features in the resistivity data.  The large dipole spikes found in the gradiometer data may possibly represent post molds or hearths contiguous to Whittlesey occupation of the area.
