Further to my previous post, I have now made a test of my field system orientation analysis method in another part of England. This time, I decided to take a chunk of the extensive late prehistoric / Roman field systems of South Yorkshire / Nottinghamshire. The section is question was south of Doncaster on the Yorks / Lincs border, plotted by Alison Deegan as part of the Magnesian Limestone ALSF NMP.
Here is the resulting bearing / distance graph, as previously constructed for the SPTA:
Hopefully, it should be apparent that this field system is much less strongly aligned on a pair of perpendicular bearings. I think that there is some north-south / east-west bias, but the pattern is much less strong than that seen in the SPTA results.
