It is quite easy to create a web page that shows a cave survey overlay on top of Google / Virtual Earth maps.
Good work!
There is only one problem - google doesn't calculate with underground in 3D - so you may not see the vertical dependencies, the caves are always on surface.

It looks like simultaneous invention all round. I'm doing something on this too. I think it should work for any paper survey that you can scan and upload, not just computerized ones output from therion or tunnel. I have a server which can do tile cutting of a large bitmap of a cave survey. It's going to be important to create a mask of transparencies so you can see it overlayed without all the whitespace outside of the cave passage. Julian T.
