Exploitation of satellite and aircraft imagery for ocean color applications is limited by the extent to which an accurate atmospheric correction can be accomplished. Characterizing specular reflection off the sea surface is one component of this correction. The WorldView-2 configuration with two multi-spectral focal planes separated by the panchromatic focal plane and a 0.2 second offset in data collection between the two multi-spectral focal planes creates a challenging specular reflection correction scenario. On June 11, 2010 DigitalGlobe, Inc. imaged the Moreton Bay, Australia region seven times between 00:26:07 and 00:27:55 GMT with the WorldView-2 sensor. The atmosphere was exceptionally clear as confirmed by AERONET data collected at the University of Queensland in Brisbane. Specular reflection varied widely among the seven images. With the rapid imaging of the sequence of images other atmospheric and oceanic variable elements can be assumed to be effectively constant making this dataset ideal for testing glint reduction techniques. Glint reduction techniques are compared to identify which technique results in the least variable image sequence of remote sensing reflectances and greatest reduction of spatial glint-induced variability within a glint contaminated image. |
