Wax Lake Delta Aboveground Biomass and Vegetation Maps from 2016

ORNL_CLOUD provides aboveground biomass and vegetation classification maps for the Wax Lake Delta in Louisiana at 5.4-meter resolution. The dataset integrates airborne hyperspectral imagery from AVIRIS-NG and radar backscatter from UAVSAR, both acquired in October 2016, to model biomass for emergent herbaceous and forested wetland vegetation. This multi-sensor approach was developed to assess capabilities for estimating biomass in coastal deltaic wetlands.

Use Cases

• Modeling aboveground biomass for emergent herbaceous wetland vegetation using integrated AVIRIS-NG reflectance and UAVSAR HV backscatter data.
• Classifying wetland vegetation types at 5.4 m resolution across the Wax Lake Delta study area.
• Assessing the combined capabilities of hyperspectral and L-band synthetic aperture radar for biomass estimation in coastal environments.
• Analyzing vegetation structure and forest composition within the Mississippi River Delta floodplain.

Strengths

• Dataset provides a high spatial resolution of 5.4 meters for vegetation and biomass mapping.
• Integrates data from two advanced airborne sensors, AVIRIS-NG and UAVSAR, for model development.
• Focuses on a specific and ecologically important coastal deltaic wetland system in Louisiana.

Limitations

• Key metadata such as row count, column names, and dataset size are unknown across all platforms.
• There is a conflict regarding the last update date, with sources reporting 2016-10-17 and 2026-03-12.
• The specific license terms under 'other-license-specified' are not detailed.
