Data comparison between two different sensors must analyze one of their several characteristics. In order to evaluate the potential of the improvements on spectral resolution of WorldView-2 sensor, the reference data must have the same spatial and radiometric resolutions, besides the same geometric and atmospheric conditions of acquisition. For most areas throughout the world, there are no available images acquired by WorldView-2 and QuickBird-2 sensors in the same date or under the same geometric and atmospheric conditions. Therefore, the combination of the bands of given sensor to simulate the bands of a reference sensor represents an attractive possibility for the handling of remote sensing data, searching for its improvement. This work presents a methodology for the simulation of the multispectral bands of QuickBird-2 sensor applying the weighted combination of the spectral bands that possess spectral overlapping with each reference band of WorldView-2 sensor. The analysis of the spectral overlapping was performed through the discretizing of the spectral curves. Visual and statistical tests were accomplished to confirm the effectiveness of the methodology.Pages: 7981-798
