Below is the interactive map that updates as I go. This contains all the locations and markers of the Roman Coins I have logged so far, their images, links to find them on the PAS and very brief info on each coin.

For LIDAR, here is the link to the LIDAR site I've been using:

Whilst it's not a specialist archaeological LIDAR survey by any means and nor is it trying to be, it gives a good, quick view of the physical landscape for much of Britain.
