Abstract: | Replying the total station trigonometric leveling and basing on the unidirectional method of the total station trigonometric leveling,we can determine the practices in different sources of error and make use of the weight during the all error of the error propagation law.Through the analysis of precision,we can summarize under the existing equipment conditions,respectively under the condition of the middle and the intermediate method,we can also determine when we can use the trigonometric leveling method substituting the three or four leveling under same conditions. |
