UAVSAR Radar Imagery for Wetland Inundation, Peace-Athabasca Delta 2017-2022

The Peace-Athabasca Delta region of Canada is covered by UAVSAR polarimetric radar imagery collected on five dates from 2017 to 2022. Data were processed to NISAR-like products with approximately 10-meter resolution and include multiple scattering components and backscatter ratios. These cloud-optimized GeoTIFFs are provided by ORNL_CLOUD for estimating wetland inundation extent.

Use Cases

• Estimate wetland inundation extent based on polarimetric scattering components.
• Analyze changes in backscatter over time based on multi-temporal imagery from 2017-2022.
• Map terrain-corrected radar signatures based on HH and HV backscatter and their ratio.
• Validate hydrological models based on geospatial radar data for the Peace-Athabasca Delta.

Strengths

• Data spans five collection dates from 2017 to 2022, providing a multi-temporal series.
• Products have a spatial resolution of approximately 10 meters.
• Includes multiple derived products such as scattering components and terrain-corrected backscatter.

Limitations

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