A Quantitative Method to Test for Consistency and Correctness in Photointerpretation
CT: A method has been developed to quantitatively test the degree of similarity between photointerpreters andlor photointerpretation variables, such as filmlfilter type, season, and scale. This method involves giving each photointerpreter the same set of photos to interpret, and then a similarity matrix is generated for each interpreter by comparing the interpretation results to the actual ground cover. It is assumed that the interpretation has been sampled in such a way as to assure that the resulting similarity matrix is representative of that interpretation. The similarity matrix is analyzed using a computer program called KAPPA, which implements a discrete multivariate analysis technique to determine if there is a significant dgference between matrices. This technique allows the comparison of individual interpreters, a test for photointerpreter consistency, and the comparison of photointerpretation variables.
