OPERA Surface Displacement from Sentinel-1 validated product (Version 1)

The Level-3 OPERA Sentinel-1 Surface Displacement (DISP) product is generated through interferometric time-series analysis of Level-2 Coregistered Sentinel-1 Single Look Complex (CSLC) datasets. Using a hybrid Persistent Scatterer (PS) and Distributed Scatterer (DS) approach, this product quantifies Earth's surface displacement in the radar line-of-sight. The DISP products enable the detection of anthropogenic and natural surface changes, including subsidence, tectonic deformation, and landslide

Access docs-verified: Open licence: Creative Commons BY 4.0. The S3 bucket is listed as Controlled Access and requires AWS credentials from ASF.

Useful for

Use cases llm-inferred: Desk-study screening for subsidence or ground movement at North American project sites · Landslide and slope-movement screening for geotechnical risk assessments · Historic ground-movement baseline (2016 onwards) for settlement risk on infrastructure projects
Audience llm-inferred: geotechnical engineers · civils engineers · GIS analysts · planners

Limitations

Constraints llm-inferred: Coverage is North America only; no UK coverage · Measures radar line-of-sight displacement only, not full 3D motion · Requires AWS credentials to access the controlled-access S3 bucket · Sentinel-1 IW-mode inputs only, from mid-2016 onwards · Version 1 product; maintenance depends on NASA and ASF
