Abstract
A method for fusion of image block adjustments for the generation of a ground control network constituting a Metric Information Network (MIN). Utilizing the subject. fusion algorithm it is possible to duplicate the results of an extremely large simultaneous image block adjustment by sequentially performing smaller image block adjustments on small overlapping areas of interest and taking the results to update a metric information network. Note, intermediate results for less than all the imagery provide usable updates to the metric information network. The result of the infusion of sequential image block adjustments into the metric information network is that one can obtain the accuracy provided by an extremely large single image block adjustment, and do so in manageable chunks or segments involving conventional computer resources.
