"One of the most common means of expressing classification accuracy is the preparation of a classifcation error matrix. Error matrices compare, on a category-by-category basis, the relationship between known reference data(ground truth) and the corresponding results of the automated classification".
-Thomas M. Lillesand

The Error Matrix Visualization Tool was designed to aid in the essential process of post classification. This tool allows the map maker to see spatially where errors of ommision and commision so as to better focus attention and resource on these locations.
