| Abstract: | This paper introduces a basic principle and calculation formula of measuring the horizontal distance and elevation difference by central hair stadia, and analyzes its measuring precision. In order to validate the correctness of the precision estimation formula, we make lots of experiments and draw a conclusion that the precision of horizontal distance measuring of the method is higher than that of routine methods. At last, we point out some cautions of using this method, and suggest that this method should be written in textbooks and put use in the field of surveying productions. |
