## MONITORING METHODS COMPARED

# Managing the right risk with the right technology

Effective geomonitoring relies on selecting the right combination of technologies.

Different methods provide different types of insight, and the most robust monitoring strategies are shaped by site conditions, risk profile and decision requirements.

Different technologies provide different types of insight. Understanding their strengths helps define the right monitoring stack.

 ![GNSS](https://www.kurloogeomonitoring.com/wp-content/uploads/GNSS.jpeg)### GNSS

 Best at Continuous, absolute 3D positional monitoring across large or distributed areas.

 Considerations Requires sky visibility and GNSS interference mitigation expertise

 ![InSar Satellite](https://www.kurloogeomonitoring.com/wp-content/uploads/InSar-Satellite.jpeg)### InSar (Satellite)

 Best at Wide-area deformation monitoring and retrospective movement analysis.

 Considerations Satellite revisit dependent results limited to a line-of-sight direction

 ![LiDAR](https://www.kurloogeomonitoring.com/wp-content/uploads/LiDAR.jpeg)### LiDAR

 Best at High-resolution surface modelling and change detection over time.

 Considerations Periodic capture and lesser accuracy than alternative methods

 ![Total Stations Optical](https://www.kurloogeomonitoring.com/wp-content/uploads/Total-Stations-Optical.jpeg)### Total Stations (Optical)

 Best at High-precision relative displacement monitoring with established line-of-sight.

 Considerations Requires line-of-sight & expert survey maintenance

 ![Ground-based Radar](https://www.kurloogeomonitoring.com/wp-content/uploads/Ground-based-Radar.jpeg)### Ground-based Radar

 Best at Real-time detection of surface movement over targeted high-risk zones.

 Considerations Line-of-sight, environmental fluctuations & higher unit cost

 ![In-situ Instruments](https://www.kurloogeomonitoring.com/wp-content/uploads/In-situ-Instruments.jpeg)### In-situ Instruments

 Best at Localised subsurface or structural measurements (e.g., tilt, pore pressure).

 Considerations Localised, limited to range of motion and non-recoverable if damaged

 [ Continue to the detailed comparison ](#comparison)## Why GNSS in Monitoring

GNSS plays a critical role in many monitoring programs by providing continuous, true 3D positional measurement without line-of-sight constraints.

- No line-of-sight required
- Continuous, all-weather operation
- Scales across large or distributed sites
- Direct 3D positional measurement
 
While GNSS provides a powerful foundation, reliable monitoring depends on network design, signal quality and rigorous processing.

  | Monitoring Characteristic | Kurloo GNSS Monitoring | Optical / Total Station | InSAR | Sub-surface In-situ Instrumentation |
|---|---|---|---|---|
| Measurement reference | Absolute (global reference frame) | Relative | Relative (LOS-based) | Relative / local |
| Displacement type | True 3D vector displacement | 3D (line-of-sight dependent) | Primarily vertical / LOS | Direction dependent |
| Monitoring frequency | Continuous | Periodic/Continuous | Periodic (satellite pass) | Continuous |
| Line-of-sight required | No | Yes | No | No |
| Coverage scale | High — distributed & large-area | Moderate | Very high | Localised |
| Environmental sensitivity | Low | Moderate–High (visibility/weather) | Moderate (decorrelation, atmosphere) | Low |
| Data continuity | Designed for continuity | Interruptions possible | Satellite revisit dependent | Susceptible to damage/loss |
| Trend detection capability | Excellent for long-term trends | Good | Good for broad-area trends | Good (point-specific) |
| Integration with other datasets | Strong (GIS, InSAR, geospatial) | Moderate | Strong | Moderate |
| Infrastructure requirements | Low field infrastructure | Requires inter-visibility, power & comms | None on site | Borehole installation dependent |

Complex or high-risk environments achieve reliable outcomes by combining technologies rather than aiming for a single technological approach.

### Kurloo GNSS Geomonitoring as a backbone

Continuous 3D GNSS measurements at key points provide an absolute reference for interpreting radar, LiDAR, and InSAR displacement trends. This stable point of truth strengthens confidence when integrating multiple data sources. GNSS monitoring may be complemented where dense spatial coverage, subsurface measurement or short-baseline optical precision is required.

### Examples of combined geomonitoring methods

- **Tailings storage facilities:** GNSS on embankments + InSAR + in-situ instruments
- **Open pits:** GNSS or ATS + radar + drone/LiDAR
- **Landslides and slopes:** GNSS or ATS + InSAR + subsurface instruments

The optimal mix depends on site geometry, failure mechanisms, and required response times.
