UAVSAR Channel Maps for Atchafalaya Basin Estuary Hydrodynamics

2016-10-16 and 2016-10-17 channel maps derived from Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) data for the Atchafalaya Basin estuary in Louisiana. This Level-3 dataset, version 2, provides spatial data on open water paths in cloud-optimized GeoTIFF format to support hydrodynamic model definition and evaluation. The dataset is hosted by ORNL_CLOUD and is present on multiple platforms, indicating its established use.

Use Cases

• Defining open water paths for input into hydrodynamic models of the estuary.
• Evaluating the performance of hydrodynamic models by comparing simulated flows to mapped channel structures.
• Studying tidal influence on channel visibility using data from consecutive low and high tide days.

Strengths

• Data is derived from specialized UAVSAR interferograms, providing detailed radar-based spatial mapping.
• Covers two specific tidal conditions (low and high) on consecutive days in October 2016.
• Available in cloud-optimized GeoTIFF format, facilitating modern geospatial analysis workflows.
• Presence on multiple authoritative platforms (nasa_earthdata, datagov) signals established importance and reuse.

Limitations

• Exact row count, file size, and complete column/attribute names are not provided by any source.
• Sources conflict on the 'last updated' metadata, with dates of 2016-10 17 and 2026-03-12 reported.
• The license is ambiguously listed as 'other-license-specified' or 'None', requiring further investigation for reuse.
