Omschrijving

Researchers have found more than 60,000 hidden Maya ruins in Guatemala in a 
major archaeological breakthrough. LIDAR Laser technology was used to survey digitally beneath the forest canopy, revealing houses, palaces, elevated highways, and defensive fortification

<Lidar is a method for measuring distances by 
illuminating the target with laser light and measuring 
the reflection with a sensor. Differences in laser return 
times and wavelengths can then be used to make digital 3-D 
representations of the target.>
