Since we have been working at Gorhambury I have only posted images of processed data! Strangely enough, people are involved in the process too. Here are some images of the team at work.
Today we ran the mag and the GPR. The mag continued it’s way south with a plethora of partials around the old boundary which protrudes into the survey area, and along the edge of the field.
Tomorrow we will continue to fill in the partials around the hedge line and work our way south. Looking at today’s survey in detail doesn’t show much in the way of new buildings.
It does, however, appear to show a very large open area to the SW of the temple. Perhaps some form of gathering place in front of the building? Hard to say at the moment, but certainly another topic for discussion. South of the hedge row there are quite a few strong magnetic anomalies, perhaps pits or hearths, but little showing in the way of buildings, as yet. Of course, the mag doesn’t show everything, A grand looking house was seen in this area (Insula XXVI, building 2, monument 445) in an aerial photograph in 1977, but we cannot see it clearly in the mag data as yet.
The GPR data takes much more processing to get good images. We did, however, survey the buildings along Street 11 (Insula XXX, Building 6) that we picked up with the mag yesterday. Here are some time-slices.
The first time slice shows the fairy rings very nicely! There are quite a few in this field.
The second, third and fourth slices show details of the buildings along Street 11. I cannot emphasize enough that these are quite crude time slices and that with a bit more time I should be able to do better!
I have put some of the time slices in Google Earth so we can compare them with the mag data.
One can go back and forth comparing the two and seeing new things in both. For example in the corner of the day 6 GPR data we have some column-like features.
Comparing this to the mag plot, we can see these features just as clearly, but in the mass of detail I hadn’t noticed them before.
Larry Conyers keeps telling me I need several PhD students to go through all the data we are collecting. I am starting to believe him!
Tomorrow we’ll be out once more collecting GPR and mag data.
