WorldView-2 data simulation and analysis results

摘要

The WorldView-2 sensor, to be launched mid-2009, will have 8 MSI bands - 4 standard MSI spectral channels and an additional 4 non-traditional bands. Hyperspectral data from the AURORA sensor (from the former Advanced Power Technologies, Inc. (APTI)) was used to simulate the spectral response of the WorldView-2 Sensor and DigitalGlobe's 4-band QuickBird system. A bandpass filter method was used to simulate the spectral response of the sensors. The resulting simulated images were analyzed to determine possible uses of the additional bands available with the WorldView-2 sensor. Particular attention is given to littoral (shallow water) applications. The overall classification accuracy for the simulated QuickBird scene was 89%, and 94% for the simulated WorldView-2 scene.
