| Abstract: | Whether elevation abnormality models are built properly has great effects on the precision of GPS level elevation survey. In this paper, judgements of markedness of fitting model parameters are studied and elevation abnormality models are built on the basis of the principle of data diagnoses. The precision of elevation of other points estimated is obviously improved. |
