Lidar technology has also allowed archaeologists to make surprising discoveries in more obscure locations. For example, in a forest near Göppingen, in the southwestern German state of Baden-Württemberg, they have found an entire system of fortifications that by no means buried or invisible at ground level. “The wall was 3- to 4-meters-high at some points,” says Jörg Bofinger, an official from the state’s Stuttgart-based office of historical preservation. “No one had this construction on their radar. It was completely unknown.” What’s more, that was the case even though the state has been systematically taking aerial images since the beginning of the 1980s. “It’s unbelievable that something like this would slip past us,” Bofinger says.
