Coastal SAV Survey with Hyperspectral and Lidar Data

Submersed aquatic vegetation (SAV) data was collected over Buttermilk and Plymouth Bays in Massachusetts during September 2010. The dataset results from a collaborative campaign using the CHARTS airborne hyperspectral/lidar system, supported by extensive ground truth sampling including bathymetry, diver surveys, and water column measurements. The data is managed by NASA and originates from a joint operation by the U.S. Army Corps of Engineers and the U.S. Naval Oceanographic Office.

Use Cases

• Discriminating SAV species using fused hyperspectral reflectance and lidar-derived bathymetry.
• Modeling light penetration and water column inherent optical properties (IOPs) for coastal waters.
• Calibrating airborne remote sensing data with diver-conducted ground truth surveys of sediment and vegetation.
• Analyzing the relationship between SAV presence and sediment reflectivity measurements.

Strengths

• Dataset is supported by a large, collaborative ground truth campaign including diver surveys, bathymetry, and laboratory measurements.
• Data collection employs a specialized airborne system (CHARTS) combining hyperspectral and lidar sensors for detailed coastal analysis.
• The dataset's cross-platform presence on U.S. government portals indicates its recognized importance for coastal research.

Limitations

• No column names, row counts, or dataset size information is provided by any source, limiting technical assessment.
• Sources conflict on license: one specifies 'other-license-specified', while others list 'None', creating uncertainty.
• The specific file formats (BIN, ISO) are listed but their structure and accessibility are not described.
