Mobile Scanning
High-Speed Coverage
Mobile scanning systems (NavVis VLX3, Leica BLK2GO) capture data while walking, covering 10x more area per day than stationary scanners.
Pros
- 10x faster coverage
- No tripod setups
- Continuous capture
- Ideal for large areas
Cons
- Lower accuracy
- SLAM drift possible
- Requires post-processing
Best For
Terrestrial Scanning
Survey-Grade Accuracy
Terrestrial (stationary) scanners deliver ±2mm accuracy from fixed positions. The gold standard for engineering, construction, and precision documentation.
Pros
- Survey-grade accuracy
- Best for detail
- Geodetic control
- Proven technology
Cons
- Slower coverage
- Multiple setups
- More labor intensive

Our Expert Verdict
Use mobile scanning for coverage, terrestrial scanning for precision. The best projects combine both approaches strategically.
Choose Mobile Scanning if...
Choose mobile scanning when you need to document large areas quickly and ±5mm accuracy is acceptable.
Choose Terrestrial Scanning if...
Choose terrestrial scanning when accuracy is critical: construction QC, engineering surveys, and detailed equipment documentation.
Frequently Asked Questions
Can I use both on one project?
Yes! Many projects use mobile for general coverage and terrestrial for detailed areas.
Which is more accurate?
Terrestrial scanning achieves ±2mm vs ±5-10mm for mobile scanning.
Which is better for BIM?
Terrestrial for LOD 400; mobile for LOD 200-300 across large areas.
