Abstract

Multispectral imaging (MSI) data acquired at different view angles provide an analyst with a unique view into shallow water. Observations from DigitalGlobe's WorldView-2 (WV-2) sensor, acquired in 39 images in one orbital pass on 30 July 2011, are being analyzed to determine bathymetry along the windward side of the Oahu coastline. Satellite azimuth and elevation range from 18.8 to 185.8 degrees, and 24.9 (forward-looking) to 24.9 (backward-looking) degrees with 90 degrees representing a nadir view (respectively). WV-2's eight multispectral bands provide depth information (especially using the Blue, Green, and Yellow bands), as well as information about bottom type and surface glint (using the Red and NIR bands). Bathymetric analyses of the optical data will be compared to LiDAR-derived bathymetry in future work. This research shows the impact of varying view angle on inferred bathymetry and discusses the differences between angle acquisitions.
