Abstract : The report describes the application of a segmentation technique for achieving compression of topographical data. A series of Monte Carlo tests is used to evaluate the quality and cost of the resulting approximation. It shows that in most instances the error due to the approximation is only a small fraction of the maximum. Therefore a large maximum error may be tolerated in the original design and thus a greater data compression may be achieved. (Author)
