TersusGNSS MVP S1 Handheld SLAM Laser Scanner: Efficiently Addressing Data Collection in Complex Forested Areas
Tersus GNSS 09 January, 2026
Lightweight & Handheld | No Control Points Required | Strong Environmental Adaptability | High-Precision Point Cloud
I. Project Background
A regional forestry survey and mapping technical service provider in Asia undertook a resource inventory task in an area featuring both plantation and natural forests. The operational area was characterized by dense canopy, poor light penetration, undulating terrain, scattered sample plots, and inconvenient transportation. Traditional surveying methods proved inefficient and costly in such environments. The client urgently needed a new data collection solution that was portable, efficient, and highly adaptable.
II. Challenges and Pain Points of Traditional Methods
Low operational efficiency, reliant on multi-person collaboration.
Cumbersome equipment, unsuitable for prolonged operations.
Severe understory occlusion makes it difficult for UAV and vehicle-mounted systems to obtain complete data.
Complex and time-consuming post-processing.
III. Solution: MVP S1 Handheld SLAM Laser Scanner
The client adopted the MVP S1 Handheld SLAM Laser Scanner, with a mobile control App and desktop post-processing software, enabling a single operator to rapidly complete 3D data collection tasks in complex forested areas with just one device.
Suitable for: Forestry inventory, topographic surveying, ecological monitoring, urban surveying, mine surveying, and other outdoor complex environment 3D data collection applications.
Core Advantages
1. Lightweight and Efficient: The entire unit weighs less than 1kg, operable by a single person.
2. Immediate Scanning: Requires no control point setup; starts collecting immediately upon power-on.
3. Strong Resistance to Occlusion: SLAM fusion algorithms are well-suited for low-light and dense tree trunk environments under the canopy.
4. Real-time Preview: View the point cloud simultaneously while scanning, allowing for on-site gap checking and supplementation.
5. High-Precision Output: Supports RTK-SLAM, delivering point cloud relative accuracy <1cm and absolute accuracy <5cm.
IV. Implementation Results
Significant Efficiency Improvement
1. A single operator can now complete plot collection tasks that previously required 2-3 people.
2. Field time per sample plot reduced by 60%-70%.
3. Multiple dispersed sample plots can be scanned continuously within the same day.
4. Reliable Data Quality
5. Point clouds of understory terrain and tree trunk structures are continuous and complete.
6. Output formats (.las / .ply / .rcp) can be directly imported into GIS and specialized forestry software for analysis.
Reduced Cost and Risk
1. Decreased reliance on large, high-cost scanning equipment.
2. Lowered operational skill barriers and training costs.
3. Avoided data fusion risks associated with multi-device operations.
V. Customer Feedback
"In complex understory environments, the MVP S1 can rapidly complete scans and obtain continuous point cloud results, significantly enhancing on-site operational efficiency."
