Your property might be at risk!

Using some of the world’s best commercial satellites, advanced processing techniques and machine learning, we derive dense virtual survey network of measurements on and around each property to help measure and visualise ground movement.

Leverage unparalleled spatial intelligence to understand how ground movement is impacting properties across Australia.


Go back in time to establish a credible baseline of movement prior to the start of construction or infrastructure projects.


Pinpoint exactly when your property might have first been impacted to help investigate what might have actually caused ground movement.


Timely measurements to help visualise movement timelines and provide temporal evidence to support your damage claim process


Through the analysis of historical and current data, monitor change to identify trends, track change and predict future outcomes.


Property report to mitigate risk for a range of industries

Property Owners

Understand and document ground movement on and around your property to support damage compensation claims.

Mortgage Lenders and Valuers

Improve the accuracy of property valuations by taking into account the potential impact of ground movement on the structural integrity of the property.


Get a more accurate risk profile for more accurate premium pricing for single or multiple properties and support the investigation of damage claims.


Assess the impact of ground movement on acquisition targets through independent insight to improve due diligence and predict potential future loss of value.

Government Agencies

Monitor the impact of infrastructure work performed by third parties to limit public liability and keep an eye on public assets that might be at risk.

Legal Firms

Leverage historical data to establish causation, support damage claims proceedings and provide credible evidence to be used in cases where damage was caused by a third party.

What is in the report?

1. Property Focused Analysis

Understand and easily visualise if and when your property was impacted by ground movement and whether your property is subject to differential (tilting) or high velocity movement.

3. Construction updates

Relevant construction updates (highlight and link to online documentation from the project proponents) to help determine whether tunnelling or excavation activities might be linked in time with the surface movement measurements.

2. Neighbourhood Assessment

Analysis of surface movement trends in areas located around the property to potentially predicting future surface movement that might impact the property.

4. Technical report

Technical overview of the techniques used to process the imagery to support any future legal proceedings.

Frequently asked questions

How is the report different than a dilapidation report?

Our report looks back at ground measurements for up to three years and provides measurements at 11 or 12 intervals, filling the gap between pre and post dilapidation reports.  With frequent revisits on the measurements, we can help identify exactly when the property was first impacted.  The report complements the information found in the dilapidation report.

How long does it take to get my report?

We typically send the report 7-10 working days from the time it was first ordered.

How far back in time does the analysis go?

In general, the analysis goes back 30 to 36 months in time with new measurements made every 11 to 12 days.

How are measurements derived from the satellite imagery?

We generate measurements using an imagery processing technique called Interferometric Synthetic Aperture Radar (InSAR).  The satellite sends active radio signal to the target which then bounces back to the satellite.  With new imagery being acquired at 11 or 12 intervals, it means we can analyse if the time if took for the wave to bounce back, if there is a difference in time between observations, we can then measure how much movement has occurred.

Do you plan to provide updates going forward?

Otus plans to update its analysis 3 times a year going forward for Australia’s largest urban areas.

Will anyone need to come visit the property?

The information included in the report is mostly derived from  the analysis satellite imagery so we do not need to visit the property to generate the report.

How is the report delivered?

The reports are sent by email in pdf format which can then be printed or kept on file for future reference.

Which satellites can be used to generate your data products?

We use data from an array of satellites and airborne platform to generate our data products.  To generate ground measurements, we use Synthetic Aperture Radar satellite, to perform change detection with typically use high resolution optical imagery captured from airborne platforms.
