Abstract : The report describes several methods designed to detect pits, peaks, passes, ridges, ravines and breaks, given an array of samples, quantized terrain elevations. The methods all use local analysis of the data; they are 'parallel' in the sense that the results at each point do not depend on results already obtained at other points. (Author)
