Hi Dom,
A long time ago I built some software into the forum to generate the maps automatically from the metbox database using the free google maps service. It was a fair amount of effort when I had free time and was programming behind the scenes on the forum a lot - so it was concurrent with building the Metbox database machinery (to support Banzai/Alan's research).
Unfortunately google withdrew the free map service some time ago, and all the maps have been offline since then.
I think there's an open source thing called Open Map View or something similar which might do something similar with some programming - if it still exists, but I've not had the time to delve into it.
So unfortunately there isn't a quick fix.
I'm hoping I may have some more time to work on these things in the new year.
Best,
Crispin
