A couple of notes.

A lot coverage in the press about the Environment Agency releasing LIDAR images online and many archaeological features have been identified by amateurs, wondering if they could be of use in identifying surface features around old mines?

I also noticed yesterday that the 25" OS maps on the NLS website have now reached up to somewhere just North of Oxford. The 6" and 25" series have several years issues of the maps from 1st Edition OS to at least 1948.

Basically yes.

Not really my bag but LiDAR has been used to help identify cave & mine features throughout Cleveland & the North York Moors for some time now. It can pick up the smallest of details so whether its a collapsed adit or the foundations of a building then in many cases, it should be successful in identifying it. Interpretation & knowing where to look is probably the key factor.

See Chris's thread regarding jet workings for illustration.

It's a shame the really high res lidar data wasn't released. Whilst it's quite good for highlighting oddities in fields (like tips and outcrops) it's not so great for smaller features.

I have already spotted a number of possible deneholes on the North Downs thanks to these. Even the lo res scans show this sort of feature. Unfortunately the coverage is patchy.
