Title: Statistical Comparison of Mapped Data: ABSTRACT

Author(s): J. E. Robinson, P. D. Willette, J. C. Brower, D. F. Merriam

Article Type: Meeting abstract


Digital contour maps of different geographic parameters of the same location can be compared by isolating similar features and then carrying out an element-by-element multiplication of map pairs. Random spatial data are gridded, then filtered to eliminate bias and unwanted information such as regional trends. The filtered maps are thus compared to produce new maps that display these spatial coherents of similar features. Filtering so tends to produce a normal linear distribution of z values that either parametric or nonparametric statistical comparisons can be used to define the overall goodness of fit.
