STATISTICAL TEST FOR EVALUATION OF THE ACCURACY OF DIGITAL MAPS FOR GEO-SPATIAL INFORMATION SYSTEM

摘要

Digital maps of Geo-Spatial Information System are very important as they are the foundation of the system and the necessity to implement and develop digital map database is increasing. But because of various different needs and requirement of different users, each has different needs of accuracy. A standard for statistical test for accuracy evaluation such as the hypothesis test is very essential under such changing environment. In this study a statistical method for evaluating accuracy of digitized maps is introduced. Using hypergeometric distribution and considering consumer risk and producer risk, a statistical method was used to decide the optimal sample size.
