LiDAR vs Photogrammetry Surveying
An expert comparison to help you choose the right equipment for your project.
| Feature | LiDAR Drone Surveying & Mapping | Photogrammetry |
|---|---|---|
| Technology | Active laser pulses | Overlapping images |
| Vegetation | Multiple returns penetrate | Surface only |
| Lighting | Works in any conditions | Requires good light |
| Accuracy | ±2-5cm vertical | ±1-3cm GSD |
| Output | Classified point cloud, DTM | Orthomosaic, DSM, 3D mesh |
| Best For | Terrain, vegetation areas | Clear sites, visual output |
| Service Pricing | $4,500 - $15,000 per project | $1,500 - $5,000 per project |
LiDAR Drone Surveying & Mapping
Active 3D Measurement
LiDAR actively emits laser pulses to measure precise distances. Penetrates vegetation, works in low light, and provides consistent accuracy regardless of surface texture.
Pros
- Penetrates vegetation
- Any lighting
- Consistent accuracy
- True ground elevation
Cons
- Higher cost
- No color/texture
- More complex processing
Best For
Photogrammetry
Photo-Based 3D Mapping
Photogrammetry creates 3D models from overlapping photographs. Excellent color/texture, lower cost, but cannot see through vegetation.
Pros
- Lower cost
- Rich visual output
- High resolution imagery
- Color/texture
Cons
- Cannot see through vegetation
- Needs good lighting
- Texture-dependent
Best For
Our Expert Verdict
LiDAR for terrain under vegetation; photogrammetry for visual documentation on clear sites. Professional teams often use both technologies together.
Choose LiDAR Drone Surveying & Mapping if...
Choose LiDAR for forested sites, utility corridors, and when bare-earth terrain is essential.
Choose Photogrammetry if...
Choose photogrammetry for clear construction sites, visual documentation, and when color/texture is important.
Frequently Asked Questions
Can photogrammetry see through trees?
No. Photogrammetry only captures the visible surface.
Which is cheaper?
Photogrammetry equipment and processing costs are typically 50-70% less than LiDAR.
Should I use both?
Yes! LiDAR for terrain + photogrammetry for visual documentation is a powerful combination.
