The bearing correlogram: A new method of analyzing directional spatial autocorrelation

Extensions of nondirectional spatial autocorrelation techniques to two dime nsions have existed for many years, but the results are difficult to compar e to the traditional nondirectional techniques and often lack ease of inter pretability. This paper reviews the traditional one- and two-dimensional sp atial autocorrelation methods and proposes a new directional method which i s both easier to compare to nondirectional methods and easier to interpret than previous directional methods.
