The LiDAR map is built for a laptop or desktop.

The Waystone web app shows bare-earth LiDAR for England and Wales, around 850,000 recorded historic places across Britain and Ireland, Roman roads and the Ordnance Survey six-inch maps of 1843–1913. It needs a big screen and is not ready for phones yet.

On a phone you can open any place's own page, with its LiDAR, its record and the places around it, from the guide to the LiDAR map.

A mobile app is coming to iOS & Android
