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.
