Transform your automatic deformation monitoring
Streamline your site monitoring
Automatic deformation monitoring is a critical service in the mining and civil works industries to detect the early warning signs of a slope collapse and act before slope failure.
Ongoing monitoring allows you to identify movement of the ground, cracks or other damage to the structural integrity of a bridge, an embankment, a cutting, a dam wall, tower or a mine or quarry slope. The changes in the speed of deformation allow you to understand if a slope is experiencing ongoing creep, if it is settling towards stability, or if it is accelerating towards collapse.
Continuous automatic deformation monitoring enables greater safety on site. Workers can be removed from the potential fall zone while action is taken to reinforce the structure.
Further, there are productivity benefits. If there are concerns about the structural integrity but automatic deformation monitoring records no defects, operations can continue safely.
Why GeoLidar for automatic deformation monitoring?
- Safety: GeoLidar monitoring takes people out of dangerous situations.
- Speed: The scanning occurs in real time.
- Comprehensive: Monitoring can produce a data-rich 3D map that can be stored for future assessments.
Deformation monitoring techniques
Current deformation monitoring techniques include manual readings taken from time-to-time by a surveyor – this is not real-time and is only for a small group of points, not whole-surface coverage. The next step up is using an automatic total station, which improves the time-per scan to several scans a day, but again only for a few individual points. InSAR monitoring from satellite is monthly or weekly scans at best. Ground based radar, such as Slope Stability Radar, is the gold standard for deformation monitoring, but it comes at a gold-plated price – it also is physically large and consumes a lot of power, meaning it is often unable to be used in difficult locations or tight spots. None of these technologies can automatically remove unwanted objects from the scene.
GeoLidar changes this.
It streams data in near-real-time, it gives precise readings like ground-based radar (but at much shorter ranges), it gives full-surface coverage not just points like survey system, and it automatically removes noise using smart algorithms. It is small enough to fit in a backpack and can be easily moved into tight locations.
