Event description
First RGG technical luncheon of the 2019-2020 season. InSAR, surface deformation ahead of the (exponential) curve

About this Event

The RGG is please to kick off our 2019-2020 technical sessions with a presentation from Tim Hartel, Manager, InSAR Field Applications of SkyGeo Inc. Tim's presentation "InSAR, surface deformation ahead of the (exponential) curve" provides some insight on InSAR, and its use for deformation monitoring of construction projects.

"Surveying has undergone step changes recently. As synthetic aperture radar (SAR) data is acquired semi-weekly literally everywhere, we are starting to build up an archive of civil engineering structures and the way they move over the course of years. We can query these dynamic patterns and connect them with the failure modes that affect these structures.

This has driven a fundamental change where Surveying has become more data science. Surveyors no longer need to decide upfront on how to deploy - their workflow has changed to a world where they can first access data and then decide on follow on, on-site surveying and monitoring strategy.

Nowadays, various Radar satellites revisit and record the earth’s surface with a revisit time of 4 to 28 days. Night and day, rain or shine, these satellites record the surface and the way it deforms. Silicon Valley is investing large sums of money into the next generation SAR satellite mission that will sample the whole world every few hours.

We show how this technology allows users to determine displacement e.g. no displacement, constant velocity (e.g. subsidence; linear), or acceleration (at first segmented and finally exponential) and connect it to structural integrity. We will show various case studies, indicating that InSAR radar images, collected and processed correctly, can detect rates of displacement on a sub mm/day scale (~0.1 ft/month), many months before cracks are visible to the naked eye, and also long before the signal exhibits a characteristic exponential acceleration leading up to failure. "

Tim H.D. Hartel

Manager InSAR Field Applications

Tim earned M.Sc. degrees in geochemistry and thermodynamics with minors in structural geology from both universities in Amsterdam and Calgary. After working in the environmental industry and as a well site geologist on the rigs, he worked for 13 years at Suncor Energy in the natural gas group. Tim has led field excursions for the CSPG and the AAPG. Since 2010 he operates Rock Proof Ltd. supporting O&G locally and internationally, with reservoir parameters (open vs closed fractures, facies, porosity and permeability) from drill-cuttings and core. The last few years he serves as InSAR application expert with SkyGeo Inc.
