LIDAR is a relatively new high-resolution tool used for surveying landscapes this technology is revolutionizing the world of archaeology. Many new archaeological discoveries are no longer dependent only on Radar. When compared with previous techniques of surveying ruins, a team in West-Central Mexico had taken 2 seasons to survey just 2 square kilometers. However, with LIDAR technology, they were able to map an entire city in just 45 minutes!.

What is LIDAR technology? LIDAR, standing for Light Imaging Detection and Ranging, makes use of laser pulses to create a detailed ground map of the surface below. This is done by measuring the differences in wavelengths and return times of each pulse to map out what the target area might look like. it is equally effective over land or over water.



Archaeologists in the past have had to hack through jungles or across desert land in search of what they are looking for. not anymore though there's is a growing number of incredible discoveries that have been made with LIDAR technology.


Many archeologists would be familiar with the sprawling Angkor Complex in Cambodia. Angkor Wat is the most famous structure in the complex, it is thought to be the largest religious structure in the world. Now with the help of LiDAR, lasers have revealed an elaborate network of undocumented temples, these extend far beyond the known Angkor Complex. this basically amounts to a finding of a lost city in the Cambodian jungles, it has provided a stack of information about Ancient Angkor, it has also shown us just how little we know about this ancient past.
