Archaeo|Rur

The app Archaeo|Rur is a multimedia guide and explains the history of the Rureifel region from the Celts to the Second World War. Above all, the Battle of the Hürtgen Forest left traces in the landscape that are still visible today. With the help of photos, videos and historical aerial imagery, the violent history of today's peaceful landscape can be experienced. After an initial download of the route data, ideally via WiFi, the app no longer needs a connection on the go.
The LiDAR terrain model makes structures visible that are otherwise difficult to see under trees and bushes. From an airplane, the earth's surface is scanned with laser beams. Some of the laser beams penetrate the canopy in wooded areas and reach the ground. With a complex calculation process, trees and houses can then be removed and a terrain model is created. The LiDAR data used here was collected by the state of North Rhine-Westphalia and is available as open data.
