Using a statistical simulation process, the behavior of the Accuracy Standards for Large Scale Maps (ASLSM) of the American Society for Photogrammetry and Remote Sensing is analyzed according to the sample size, as well as the relation between the limiting errors (thresholds), stated by the standard as a root mean squared error, and the actual root mean squared error of the product. When the root mean squared error of the product equals the threshold of the standard the simulation results show the ASLSM is very restrictive, classifying 75 percent of products as Class 2 maps instead of Class 1 maps. If the variability of the product is greater or lesser than this threshold, results can be depicted by a family of acceptance curves. These curves can be employed by users to determine the sample size needed to limit their acceptance risk, but also by producers to analyze their rejection risk. |
