LiDAR vs Photogrammetry
Understanding when to use LiDAR versus photogrammetry for your 3D capture projects.
LiDAR
Specifications
Accuracy
±1-3cm typical
Works in
Any light
Vegetation
Penetrates
Output
Point Cloud
Pros
- Works in any lighting conditions
- Penetrates vegetation (forestry)
- Highly accurate measurements
- Direct georeferencing
- Faster data processing
Cons
- Higher equipment cost
- No color/texture data alone
- Heavier payloads for drones
- Limited to line-of-sight
Best For
Topographic surveys, forestry, power line inspection, night operations
Photogrammetry
Specifications
Accuracy
±3-5cm typical
Works in
Good light only
Vegetation
Surface only
Output
Point Cloud + Texture
Pros
- Lower equipment cost
- Rich color/texture data
- Lightweight sensors
- High-resolution orthomosaics
- Familiar camera technology
Cons
- Requires good lighting
- Cannot penetrate vegetation
- Longer processing times
- Requires ground control for accuracy
Best For
Construction progress, roof inspections, visual documentation, marketing imagery
Our Verdict
The choice depends on your project requirements. LiDAR excels where accuracy is paramount and lighting is variable. Photogrammetry is ideal when visual quality matters and budgets are tighter. Many professionals use both technologies together for the best results.
