  • Movement maps and uncertainty report
  • Threshold observations and escalation log where commissioned
How we deliver

Scope & options

Deformation monitoring measures displacement relative to stable control; uncertainty must be smaller than the movement that matters.

Ground instruments, repeat scans and InSAR observe movement differently and can be combined for different spatial/temporal scales.

Action thresholds are engineering decisions tied to asset risk, not generic website values.

Explore 4 service variants

GNSS, total-station and levelling monitoring

Measure repeat positions/levels against stable references.

Reference stability and observation frequency must suit the hazard.

Repeat TLS/UAV surface comparison

Compare surveyed geometry across dates.

Registration and detection limits must be adequate for the expected movement.

Satellite InSAR deformation analysis

Interpret radar observations of line-of-sight surface movement.

Geometry, coherence, revisit data and ground validation limit interpretation.

Slope and rock-face engineering inputs

Provide measured geometry for geotechnical assessment.

Mapping does not by itself certify slope stability.

Useful to know

Terms, explained
Benchmark
Stable reference used to measure movement over time.
Displacement
Change in position between observations, reported with direction and time.
Slope monitoring
Repeat measurements and engineering interpretation used to track potentially unstable ground or faces.
Can you guarantee warning before a failure?

A monitoring system has measurement, coverage and response limitations. A responsible engineer must define the monitoring and emergency-response plan.

Is satellite movement the full movement in every direction?

The method measures an intermediate quantity that requires interpretation. InSAR primarily measures displacement along the radar line of sight; additional geometry or ground data is needed for broader interpretation.

Can ordinary progress photographs detect small settlement?

The method must resolve movement at the scale that matters to the asset. Control stability, observation frequency and measurement uncertainty are designed around that threshold.

Who decides when an alert should trigger action?

The asset owner’s competent engineering and safety team sets the thresholds and response responsibilities. Lotusmirk coordinates the contracted measurement/reporting workflow.

Method & limitations

Select ground instruments, repeat scans or satellite methods for the movement question.

Separate measurement uncertainty from observed displacement.

A competent engineer defines thresholds and the action plan for safety-critical monitoring.

Reference stability and observation frequency must suit the hazard.

Registration and detection limits must be adequate for the expected movement.

Geometry, coherence, revisit data and ground validation limit interpretation.

Mapping does not by itself certify slope stability.

Help me ask
  • What movement and uncertainty does the monitoring system need to detect?
  • Which references are stable enough for repeat measurements?
  • Who will set thresholds and respond to an alert?
Use ordinary words. A short problem description is enough. Do not include confidential or security-sensitive information.
Start with state and district/city. Exact boundaries can be provided later through an agreed channel.Leave blank if unknown.
An estimate is acceptable. Leave unknown rather than inventing a measurement.Leave blank if unknown.

Personal addresses are accepted for civilian enquiries and individual training.
More project detail Optional
State only a non-sensitive reference. A submitted standard is a requirement to review, not a claim of accreditation.
Examples: ground-only work, no cloud hosting, limited access. Do not include personal IDs, confidential documents or sensitive locations.
Provide the tender/design requirement, not an invented target. Image resolution and positional accuracy are different.Leave blank if unknown.
Unknown is acceptable. Apply WGS84/UTM or a local benchmark only when it is confirmed for the job.Leave blank if unknown.
