Maps provided by the Environment Agency (EA) have helped a team of amateur archaeologists to find an old Roman road in the northwest countryside of England. The maps are often used to determine the risk for floods in the areas. The EA has been using the technology of creating maps by laser scanners fitted over the aircraft. The technology has been utilized over decades to map the landscape of England.
The data gathered through this technology was made available to public, starting from 2013. The newly-rediscovered road is approximately 23 miles long. The Roman road found in Lancashire is the first one to be revived in about 150 years, according to 70-year-old David Ratledge. He added that the Lidar technology was instrumental in discovering this extremely sensible and cost-effective trough through Longridge and Inglewhite to Catterall, near Garstang. It seems like decades-long puzzle has been solved, he further stated.
The existence of a road from Ribchester to Lancaster has always been considered, since they were the county’s extremely significant Roman locations. The discovery would have been next to impossible without the use of Lidar. The technology is capable of accurately identifying alleviated ground and is much more proficient in tracing a route as compared with human eyes.
“Our current Lidar system can record up to 550,000 heightened coordinates per second. This gives an extremely dense network of accurate ground points that can be triangulated to give highly detailed elevation grids,” said EA’s Susan Winter. She added that the system is suitable for archaeology, managing forests and developing computer game worlds.
The RT notes that, Amateur archaeologists have discovered a lost Roman road in England’s northwest countryside by using maps provided by the Environment Agency (EA) for assessing areas at risk of flooding. The maps were created by aircraft equipped with laser scanners, a method used by the EA to map England's landscape for decades.
The data, however, has only been freely available to the public since 2013. Now a group of amateur archaeologists have uncovered a “new” Roman road, about 23 miles in length.
In other news Dailymail reported, 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.
In a statement provided to Metro, Hugh Toller, an archaeologist specialising in Roman Britain, used the lidar data to reveal roads going from a fort at Low Borrowbridge in Cumbria to the site of a Roman cavalry camp in Kirkby Thore – the missing piece of a well-known Roman road going towards Carvoran Roman fort near Hadrian’s Wall.
‘Often there are vague indicators of a route but not enough evidence to be sure,’ he said. ‘With lidar we can spot any “aggers” – a Roman embankment or rampart. ‘If you find 2km or 3km of these running dead straight, there is nothing it can be except a Roman road.’
