Paper Abstract
Multispectral imaging (MSI) data collected at multiple angles over shallow water provide analysts with a unique
perspective of bathymetry in coastal areas. Observations taken by DigitalGlobe’s WorldView-2 (WV-2) sensor acquired
at 39 different view angles on 30 July 2011 were used to determine the effect of acquisition angle on bathymetry
derivation. The site used for this study was Kailua Bay (on the windward side of the island of Oahu). Satellite azimuth
and elevation for these data ranged from 18.8 to 185.8 degrees and 24.9 (forward-looking) to 24.5 (backward-looking)
degrees (respectively) with 90 degrees representing a nadir view. Bathymetry were derived directly from the WV-2
radiance data using a band ratio approach. Comparison of results to LiDAR-derived bathymetry showed that varying
view angle impact the quality of the inferred bathymetry. Derived and reference bathymetry have a higher correlation as
images are acquired closer to nadir. The band combination utilized for depth derivation also has an effect on derived
bathymetry. Four band combinations were compared, and the Blue and Green combination provided the best results.
