Uncertainty description of random error point in GIS

CAI Jian-hong①②,LI De-ren①③(① School of Remote Sensing and Information Engineering,Wuhan University,Wuhan 430079,China;②College of Resources and Environmental Sciences,China Agricultural University,Beijing 100193,China;③ National Key Laboratory for Information Engineering of Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079,China)  
Considering simple and convenient computation,uncertainty description in GIS analysis and decision-making,in this paper,many methods of describing positional error and confidence levels of them accordingly were enumerated,at the same time the abstract point quality visualized with 2D(3D) graphics were embodied.In order to simplify confidence level computation,the confidence level of k correspondingly describing error ellipse or ellipsoid was adopted,and through analyzing and comparing the different description manners,a conclusion was made that among description manners,positional mean direction error(PMDE) and error interval were easy to describe positional precision with practical,flexible,complementary characteristics.
