Contextual versus one-size-fits-all InSAR

Interferometry is a proven tool for assessing minute changes of the earth’s surface over wide areas. SAR images over large parts of the world have been processed  – and a lot of these processed data are in the public domain. InSAR data are no longer scarce – but does that mean you can use them?

You have seen InSAR presented in PowerPoint as a layer in GIS, along with other satellite imagery. In other words: as a “one-size-fits-all” process, based on a cloud-based processing chain for converting SAR images to a photo. But InSAR processing is not like Photoshop, there is an infinite number of InSAR processing strategies, and the only way to constrain and optimize the outcomes of the processing is by applying geodetic estimation theory.

Unconstrained processing gives you non-specific, unusable results that are only good for initial showcasing and generating initial awareness – therefore we use it for rapid prototyping potential projects only.

Only you and your users with (non-InSAR) domain expertise can give us that input to constrain. So in order to deliver reliable results, our InSAR and geotechnical engineers work closely with your team to understand the asset, its surroundings and what is physically possible.

We fine-tune our data processing procedures based on your input about the geotechnical risks and your business goals. Instead of giving you one-size-fits-all photos of undetermined geodetic quality in a 1-way transaction,  we have a 4-step process to give you tailor-made information products.

This is SkyGeo’s unique vision:  after the initial one-size-fits-all processing, we work with you and get your input to make a usable end-product to make sense of your geotechnical realities.

All InSAR vendors use the same data source. The difference is in the data processing methods, the quality of the algorithms and the geotechnical expertise of the InSAR engineer.

Interpret ground motion

Assess geotechnical risk early with help from our experts.

Millimeter accuracy

Time series show how objects have moved on millimeter-scale. We help you separate the signal from the noise.

Constant updates

Your data are updated as often as satellites acquire an image, up to 5 times per week or as often as you need for your business.

Geotechnical domain experts

Our geotechnical experts monitor risk for all kinds of assets, large and small – all over the globe.

High density measurements

Our maps contain up to 100,000 measurements per km2, to complement local monitoring campaigns.

Recordings since 1992

Understanding long term trends allows you to extrapolate further into the future.

Intuitive platform

Access your data on our platform and assess where your assets are most at risk.
