UAVSAR: Repeat-Pass Interferometry Scenes

UAVSAR_INSAR_INTERFEROGRAM is a dataset of repeat-pass interferometry scenes from NASA's UAVSAR platform. The data is hosted by the Alaska Satellite Facility (ASF) on the NASA Earthdata platform. The scenes are likely used for measuring surface deformation from radar phase differences.

Use Cases

• Modeling ground displacement from earthquakes or volcanic activity (inferred from domain, verify after download)
• Monitoring infrastructure stability, such as dams or bridges (inferred from domain, verify after download)
• Generating digital elevation models (DEMs) from radar interferometry (inferred from domain, verify after download)

Strengths

• Published on the authoritative NASA Earthdata platform.
• Provided by the Alaska Satellite Facility (ASF), a known data distributor for SAR missions.

Limitations

• Metadata is minimal; actual content requires verification after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.

Provenance

Source

NASA UAVSAR platform, distributed via Alaska Satellite Facility (ASF).

Collection Method
