Study on Accuracy and Precision

Abstract

The public surveying standard of Japan introduced JPGIS (Japan Profile for Geographic Information Standards) based on ISO (the International Organization for Standardization) and JIS (the Japanese Industrial Standard) in 2008. JPGIS regulates “accuracy” as the quality definition of the datasets, however “precision” is commonly used for the quality evaluation in the standard. This report expounds definition with respect to “accuracy” and “precision” including numerical examples.
