Optimize your geohazard resource allocation with with our 3D ICP lidar change detection
WATCH THE DEMOCambio lidar change detection enables reliable and cost-effective geohazard detection, monitoring, and analysis for large areas
Method 1: DoD
Time to detect: 12 years
Limit of detection (LOD): -0.60m to +0.65m
01
Digital Elevation Models (DEM) of Difference/DOD
This 2D view is common but insensitive [high limit of detection] producing results that can be hard to trust.
Method 2: 3D, no ICP
Time to detect: 8 years
Limit of detection (LOD): -0.40m to +0.55m
02
3D with No ICP Alignment
This 3D view provides some improvement in limit of detection.
Method 3: 3D ICP
Time to detect: 4 years
Limit of detection (LOD): -0.20m to +0.15m
03
3D with Iterative Closest Point
Using ICP reduces limit of detection by 3-5x, providing results you can confidently make decisions with and identify geohazards before they threaten the integrity of your asset.
Cambio’s 3D ICP lidar change detection provides

- Earlier detection of new hazards (4 years vs 12 years with traditional methods)
- Coverage of large areas at lower costs
- Ability to identify hazards not visible in field visits
- Detection of landslides that can stress pipelines over months/years/decades
- Screen out sites that don’t need field visits
- Analytics tools like advanced elevation profiles and change statistics to better understand the severity of geohazards
- Additional contextualized datasets that can be layered on such as satellite imagery, precipitation, red relief, contours, hill-shading, and slope gradient to help visualize a more comprehensive picture.
