Soil resistivity data

Hi all

A couple of times recently (example) there’s been mention of the BGS soil electrical resistivity model. I looked it up (here) and indeed it does look like a helpful resource as a first-pass check prior to - and a sense check for - a proper survey. But the pricing model direct from BGS isn’t sensible for a single site due to handling fees and they’re not replying to emails anyway... has anyone got experience of actually using the data or an alternative and where was it obtained from?

Sparkingchip‍ mentioned that he’d seen a wall poster available which would be ideal. But I can’t see where he’d get it from?

Thanks all.

Agreed we could "just" measure it, and in due course that will need to be done ... and indeed that's what's currently done (with Wenner method, generally coinciding with some other surveys). But we have to wait (and pay) for that, and I just wondered if you could get a sneak peak at an indication of what the site's like from the desktop to help with preliminary studies, and it might possibly also help with planning the survey and later interpreting the results and selecting possible electrode locations when read in conjunction with the actual site measurements.

As an aside, the user notes do say results are given on a 50m grid, which given that the minimum order is 1km and I do get to see some pretty large sites is fine with me.

Would love to know if anyone's used it though.
