Changing recording patterns

I’m not sure how interested you’ll be in the below, but I’ve just been plotting some GIS of the changing picture that the recording of objects through the Scheme has given to our national chance find distribution.

Finds from 2003 Finds from 2003 - 2004 Finds from 2003 - 2005 Finds from 2003 - 2006

From left to right, the plots are:
a) All finds for 2003
b) All finds for 2003 to 2004
c) All finds for 2003 to 2005
d) All finds for 2003 to 2006

I then plotted two other GIS outcomes using the CCI data that I have been manipulating for Phil de Jersey and another set of recently released data, the Guest and Wells “Roman coins from Wales” data. This can be downloaded direct from the ADS website.

CCI data set plotted over PAS data set Guest and Wells’ dataset over PAS

The above maps are ordered as left - CCI over PAS and right - Welsh Roman coins over PAS.
This can then be zoomed in to show just our Roman coins compared to Guest’s Roman coins from Wales. Quite a discrepancy!
