A bit off topic I know but useful to show the kinds of thing that can be done with OpenSpace.
As ever, feel free to reuse code snippets etc for cave map related purposes.

I have made what I believe is a useful web page for the UK outdoors
community (hikers, mountain bikers, horse riders, climbers ... ).
It uses OS mapping and Google imagery to enable the route of a path,
track, road or street on the OS mapping to be located on the imagery
and vice versa.
There are no adverts on the page. I do not think it significantly
promotes the business of Google. So I believe it is within the spirit
of the OpenSpace Developer Agreement.
A similar solution could be engineered with OS imagery if the
OpenSpace API included it. 1:25K mapping would be good too.

The Ordnance Survey Openspace API requires 'HTTP referrers'. If you get 'HTTP referrer' errors, you will
have to enable them in your browser and/or internet security software before the demo will work.
