Claim One:
1. A method for processing remotely acquired imagery, comprising: receiving a first set of imagery data and a first set of associated metadata, said first set of imagery data defining a first image of a panchromatic image type, said first image having a first spatial resolution and a first spectral resolution; receiving a second set of imagery data and a second set of associated metadata, said second set of imagery data defining a second image of a multi-spectral image type, said second image having a second spatial resolution less than said first spatial resolution and a second spectral resolution greater than said first spectral resolution; obtaining at least a first mapping function specifying a mapping between pixels in said first image and pixels in said second image based on at least said first and said second sets of associated metadata; generating a third set of imagery data defining a third image of a panchromatic type based on said second set of imagery data, said third image having said first spatial resolution and said first spectral resolution; generating an alternate mapping for said first and said second sets of imagery data based on comparing at least a first area of said pixels in said first image and at least a first area of said pixels in said third image that are spectrally non-corresponding areas that are spatially corresponding according to said first mapping function; and generating a fourth set of imagery data defining a fourth image based on said first and said second sets of imagery data and at least said alternate mapping, said fourth image having said first spatial resolution and said second spectral resolution; wherein said generating said fourth set of imagery data further comprises: obtaining at least a second mapping function based on said first mapping function and said alternate mapping; combining said first and said second sets of imagery data according to said second mapping function to obtain said fourth set of imagery data; computing radiance values for a first area of said fourth image corresponding to said first area of said first image based on radiance values for said first area of said second image specified in said second mapping function; and computing radiance values for a second area of said fourth image corresponding to said first area of said second image based on radiance values for a plurality of pixels in said second image surrounding said first area of said second image specified in said second mapping function.
