Preliminary results from a system comprised of an inertial navigation system and an aerial camera which are hard mounted together indicate that position estimates may be obtained which are in error by no more than 2.2 metres (1 sigma confidence limit). The system which has been developed by the Canada Centre for Remote Sensing in conjunction with the Department of Surveying Engineering of the University of New Brunswick for the Canadian Hydrographic Service, was originally conceived to complement water-borne hydrographic charting procedures in shallow water areas. Clusters of ground targets spaced at appropriate flying time intervals are used to correct the errors of the inertial navigation system in post-flight processing, thereby enabling highly accurate position estimates for those photographs which do not contain ground targets. Thus, the system is ideally suited for coastal mapping where complete ground control coverage would be very expensive and often impractical. Also, the system has good potential for conventional photogrammetric mapping projects where ground control targets could be set in clusters at appropriate intervals.
