Abstract:	Integrating GPS with an inertial navigation system (INS) allows for direct image georeferencing, offering the possibility of relaxing the demand for aerial triangulation in airborne surveying - mapping. This paper reviews the performance of the prototype Airborne Integrated Mapping System AIMS, based on GPS/INS/CCD charge-coupled device integration, developed by The Ohio State University Center for Mapping. A brief description of the essential features of the integrated system and its practical implementation is presented. The performance of AIMS TM is assessed primarily on the basis of photogrammetric processing of 1:6,000 large-scale aerial imagery considered as a truth reference. An accuracy analysis and discussion of the impact of direct orientation and multisensor system calibration on the photogrammetric data extraction process are also presented.
