A block of 24 overlapping synthetic aperture side-looking radar images flown over a well-mapped area of about 90,000 km**2 covering parts of Ohio, West Virginia, Virginia, and Kentucky provided an opportunity to evaluate the mapping accuracy achieved in current radar mosaicking projects. An estimate was obtained for the effect of the distribution and density of ground control points and for the accuracy of different mosaicking methods that are currently employed with synthetic aperture radar images. It is shown that a successful radar mosaicking process requires the elimination of image errors of up to several kilometers. An example of a radar mapping effort in which the navigation errors could be eliminated is presented.
