During the standard geo-rectification processing of MISR imagery, all four spectral bands belonging to each of the nine MISR cameras are required to be geolocated and co- registered automatically to approximately one pixel accuracy. Two steps of processing are designed to accomplish this goal: (1) a complex multi-camera geolocation and co- registration of the red spectral band data for all nine cameras, and (2) the co-registration of the other three spectral bands of MISR imagery of each camera using their relationship with the already geolocated red band imagery. This paper addresses the second processing step. The geometry of the satellite orbit, the ellipsoid rotating earth, and the separation of the view angles between different spectral bands are combined in a mathematical model which describes the band-to-band line and sample parallaxes. The sensitivity study of this model to numerous error sources, such as variations in the orbit and earth radius, orbit perturbation, and navigation errors, leads to a practical polynomial band-to-band transform solution, and the decision on the usage of either a static or dynamic band-to-band transform as well as the application range of the transform
