Statistical Analyses of Ocean Terrain and Contour Plotting Procedures

摘要

This report illustrates the application of statistical analyses to the characterization of terrains and to the evaluation of methods for producing contour maps from measured values. The statistical nature of a terrain is shown to have an important bearing on the relative accuracy of alternative interpolation procedures which might be used in contour mapping of the terrain. Methods of interpolation, using three or four data points to arrive at each interpolated value, are examined in detail and shown to be substantially as accurate as more complex methods. (Author)
