UK Flood map reveals lost Roman Roads

Hi-tech Lidar data reveals the route of 2,000-year-old highways across Britain
Aerial flood maps of Britain are revealing more than just at-risk regions - they have also led to the discovery of several Roman roads.
Amateur archaeologists have been able to use the flood-mapping technology to trace the paths of Roman roads which have remained buried under the land for some 1,600 years.
The aerial flood maps were created by aircraft equipped with laser scanners which measure the distance between the aircraft and the ground.
Using light detection and ranging (Lidar) technology, the Environment Agency was able to detect the areas of Britain which are most at risk of flooding.
The precision technology can detect differences in the height of the land of as little as 5cm, making it ideal for detecting hidden structures buried under the soil.
Although the Environment Agency has been using the technology for some 20 years, it was only made freely available to the public in 2013.
And in just two years, teams of archaeologists have already unearthed seven long-lost Roman roads across the country.
