This is a long-preview flag that next April I will be walking the length of Hadrian’s Wall. This exercise will have two aims: firstly, (hopefully) to work with the Pleiades project to see how direct GPS observation can support/contribute to the connected datasets they hold; and secondly I’m hoping to raise some cash for Cancer Research UK. Any ideas for the former, and/or any sponsorship for the latter, would be very welcome (options of how to give will be posted here shortly).
