  • Description:
    When the data in a photogrammetric block-bundle adjustment is ordered in the most advantageous manner the resulting normal equations have a banded structure for which both storage and computer time is near minimal. Several algorithms designed to reduce bandwidth, profile, or fill are compared using a hypothetical photo block in search of an automated method that would improve on the manual process of cross-strip numbering. None of the algorithms investigated could be considered superior to manual sorting in all respects, and therefore, a heuristically derived algorithm is proposed that will duplicate optimum manual sorting in an ideal case.
