GPR and ERT georeferencing and preliminary image

So, another day on the GPR and ERT data for Portus. Most of the morning spent checking the coordinates for the three local grid systems we are using for the data at Portus, and checking preliminary images of the GPR in a few locations. The aim here is to establish a new GIS for the geophyscial survey data to allow full integration of all of the datasets. Some interesting features in the results so far, working with data processed by Jessica Ogden at L-P Archaeology @jessogden and ncorporating earlier survey and excavation plans of the Soprintendenza.
