ISPRS 2003 A Systematic Approach for Optimizing Spectral and Spatial Matching Between Independent Datasets
In the field of Earth observation and planetary exploration, a number of spacecrafts have been equipped in the last years with various multispectral and/or hyperspectral optical instruments spanning the ultraviolet-visible-near-infrared spectral domain. In this context, a long-standing and recurrent problem in the field of planetary remote sensing lies in the combined use of independent datasets, with the frequent case of one dataset being taken as a reference. We propose a general methodology which provides both an optimized matching and also an associated estimate of its spatial and spectral stability and uncertainty. This algorithm can be applied indifferently to either 1) assess the quality of the photometric calibration already performed, establish its uniqueness and determine whether it is optimal or not; or 2) carry out the “calibration”, at the level of quality of the reference dataset. Our method is presented here with an example of calibration of a Clementine multiband mosaic of the Aristarchus plateau on the Moon, using Earth-based telescopic visible-infrared spectra as references.
