Mapping islands, reefs and shoals in the oceans surrounding Australia

The author has identified the following significant results. The geometric accuracy test produced an estimate that the distortion levels on LANDSAT imagery are such that few corrections, or possibly no corrections, would be necessary in order to have the imagery satisfy accuracy specifications. It can be expected that the geometric accuracy of the low generation imagery, being used in distortion tests, in such that the distortions would cause no difficulty during the course of map preparation.
