Quantitative comparison of contour maps

摘要: Maps can be quantitatively compared by using trend-surface analysis to simplify complex situations and then studying the components. Relationships of configuration one map another (geologic structure in this example) easily found equation coefficients well-fitted first-, second-, third-degree trend surfaces determine similarity between any pair maps, cluster similarities allows construction dendrograms. This method subtle differences maps emphasized objectively permits a more meaningful original data.
