VARIANCE ANALYSIS METHOD FOR ESTIMATION OF UNCERTAINTY APPLIED TO MAP DIGITIZATION

TAO Benzao 1 LU Xiuqin 2 (1 Key Laboratory of Geospace Environment and Geodesy, Ministry of Education; 2 School of Resource and Environment Science, Wuhan University, 129 Luoyu Road, Wuhan 430079, China)  
A variance analysis method is used to estimate the synthesis variance of coordinate data in map digitization. The determination of confidence coefficient k in the estimation of uncertainty is studied. And its calculation method is given. Finally, an example of map digitization shows the way to use this method.
