Surveying & LiDAR
LiDAR Drone Topographic Survey
Bare-earth elevation models even beneath trees and brush.

What is lidar topographic surveys?
Drone LiDAR topographic surveys fire laser pulses that reach the ground through tree canopy, producing accurate bare-earth elevation models and contours for engineering, drainage and land development.
Benefits
- Sees through vegetation
- Dense, accurate elevation data
- Large areas per day
- Contours and DEMs
How it works
- [ 01 ]Ground control setup
- [ 02 ]LiDAR flight
- [ 03 ]Point-cloud classification
- [ 04 ]Surface, contours and CAD deliverables

Who uses lidar topographic surveys — and what it saves
- Civil engineers
- Land developers
- RMs and municipalities
- Farmers planning drainage
| Factor | Traditional method | With a drone |
|---|---|---|
| Data density | Individual GPS shots | Millions of points |
| Under trees | Slow line-of-sight work | LiDAR reaches the ground |

Frequently asked questions
+Does a LiDAR drone survey replace a land surveyor?
It supplies dense elevation data; legal boundary surveys still require a licensed land surveyor.
