Drone LiDAR Through Trees

Can Drone LiDAR See Through Trees?

 

One of the biggest advantages of aerial LiDAR is its ability to collect terrain information beneath vegetation.

​

Unlike traditional aerial imagery alone, LiDAR sensors emit laser pulses capable of penetrating gaps within tree canopies and brush. Some of these laser returns reach the ground surface and can be used to generate accurate terrain models beneath vegetation.

​

This capability makes drone LiDAR extremely valuable for:

​

• Topographic surveys

• Utility corridor mapping

• Forestry projects

• Land development

• Environmental projects

• Infrastructure planning

​

​

​

Why Photogrammetry Alone Often Struggles

 

 

Photogrammetry relies on visible imagery. In heavily wooded environments, aerial imagery typically captures only the tree canopy rather than the ground beneath.

​

This can result in inaccurate surface models when vegetation is dense.

​

LiDAR provides a significant advantage by allowing ground returns to be extracted from beneath the vegetation canopy.

LiDAR Classification and Terrain Extraction

 

Modern LiDAR workflows involve advanced point cloud classification processes used to separate:

​

• Ground points

• Vegetation

• Structures

• Utilities

• Noise

​

At SKYMAPTEK, LiDAR classification workflows are utilized to generate accurate terrain models and engineering-ready deliverables even in challenging environments.
