| Abstract: | Mistakes maybe exist in various surveying work. If the restriction condition is available in a survey, the mistakes existed could be detected and picked out. But if not, especially for underwater topographic survey, because of invisibility of underwater topography, it becomes difficult and impossible for surveyor to detect that mistakes according to ones experiences, thus, the mistakes will keep company with the survey on, and causes the results wrong. In this paper, with the mistakes existed in primary data for sub-aqueous survey, the causes was discussed firstly. Furthermore, formulas for correcting wrong surveying results due to the mistakes of primary data were derived. Finally, the formulas were verified by using some surveying results. Verification result indicates that the method of correcting wrong results with the formulas proposed in this paper is both proper in theory, and also easy to operate in the field. |
