How Lidar Technology in Archaeology Works

Lidar technology employs a laser sensor that sends out light pulses to measure distances. This method involves several key steps to gather accurate data efficiently. Here's how the process unfolds:

Emission of Light Pulses: The lidar system emits millions of laser pulses per second towards the ground.
Detection of Echoes: These pulses bounce back after hitting surfaces, and the sensor captures the return signal.
Distance Calculation: Using the time taken for each pulse to return, the distance to each point on the surface is calculated.
3D Mapping: The data is processed into highly detailed 3D maps, offering insights into topography and potential archaeological features.

Such digital maps allow archaeologists to detect features like ancient roads, buildings, and agricultural terraces.

Light Detection and Ranging (Lidar): A remote sensing technology that utilizes laser light to map the surface of the Earth, offering high-precision, three-dimensional images of topographical features.

In certain challenging environments, lidar is indispensable. Think dense forests or heavily overgrown areas, which are often difficult to survey with conventional archaeological techniques. For instance, in the dense tropical forests of Central America, lidar has revealed extensive, complex Mayan city layouts that were once obscured by thick vegetation. With lidar, you can analyze terrain at different scale resolutions, identifying minor features such as small mounds that could signify buried ruins. This has led to the discovery of previously unknown sites without disturbing a single leaf, preserving the landscape for future inquiries.
