InSAR – Coverage Maps of Sample Legacy InSAR Products

ASF has processed approximately 700 sample InSAR products and made them available for download via the SSARA API. The sample products cover portions of the following Geohazard Supersites: Hawaii, Los Angeles, and Marmara. The standardized products are each processed using ROI PAC and distributed in HDF5. User feedback is encouraged.

InSAR – Collaboration

InSAR Access — API Among ASF’s many collaborations, University NAVSTAR Consortium (UNAVCO)/Western North American InSAR (WInSAR), the Alaska Satellite Facility (ASF), and the Jet Propulsion Laboratory (JPL) worked on an information technology and data-management development project to design and implement a seamless distributed access system for synthetic aperture radar (SAR) data and derived interferometric data …

InSAR

Differential interferometric synthetic aperture radar (InSAR) is used to measure displacements on Earth’s surface to a precision of a few centimeters or less. InSAR data are largely used to study deformation caused by earthquakes, volcanic eruptions, glacier movements, landslides, and subsidence.
