LiDAR - Yenra

LiDAR stands for Light Detection and Ranging. It is a sensing method that sends out laser pulses and measures how long they take to return, creating dense three-dimensional point clouds of terrain, vegetation, buildings, or other physical surfaces. In archaeology, airborne and drone-based LiDAR are especially useful because they can reveal subtle earthworks, ditches, mounds, walls, and other landscape traces that are difficult to see in ordinary photography.

How AI Helps LiDAR Work

AI makes LiDAR more useful by helping classify point clouds, segment terrain features, prioritize candidate sites, and reduce the amount of manual review needed across large survey areas. In practice, LiDAR workflows often overlap with remote sensing, computer vision, change detection, and a geographic information system. The model can surface patterns quickly, while archaeologists or other domain experts verify whether those patterns are culturally meaningful.

Why It Matters

LiDAR matters because the terrain itself often preserves evidence that people cannot easily recognize at ground level. Under forest canopy or across very large landscapes, even experienced survey teams can miss low-relief archaeological features. LiDAR gives researchers a non-invasive way to search broad areas, but it still requires careful interpretation because erosion, logging, roads, and other modern disturbances can create false positives.

Where You See It

LiDAR appears in archaeology, surveying, forestry, infrastructure mapping, autonomous navigation, and environmental monitoring. In archaeology, it is especially useful for landscape-scale prospection, mapping buried or overgrown features, and supporting field survey planning.
