Shadowmark Maps
LiDAR relief maps of Britain's earthworks. Shadowmark Maps puts national LiDAR terrain shading on one map, so banks, ditches, mounds and old roads stand out: hillforts, barrows, Roman roads, deserted villages and field systems that are hard to see on the ground or in aerial photos.
The app is for iPhone and Android phones, and is coming soon to the App Store and Google Play.
