The upper and lower stadia hair readings on a stadia rod held at station B were observed as 3.50 and 1.00 m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.5. The height of the instrument above station A is 1.45 m, and the rod reading is taken at 2.25 m. Determine the horizontal distance between points A and B, and the elevation of point B, if the elevation of point A is 155.54 m, above mean sea level.

A line of three-wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 2097 m. The instrument had a stated compensator accuracy of pm 1.4 mm/ km. The instrument–rod combination had an estimated reading error of 0.4 mm per 40 m. Sight distances were kept to approximately 50 5 m. If the observed difference in elevation is 15.601 m, what is the estimated error in the final elevation difference? If benchmark Gloria had a fixed elevation of 231.071 m and Carey had a fixed elevation of 246.660 m, did the job meet acceptable closure limits at a 95% level of confidence?

A stadia measurement was undertaken with a theodolite having an internal focusing telescope and stadia interval factor of 98.8. When a backsight was taken on a turning point whose elevation is 205.62 m, the rod interval observed was 1.94 m; and with the horizontal hairs set at 1.50 m on the rod, the vertical angle reading was -13 degree 45’. For a foresight to a control point, the rod intercept was 1.17 m; and with the horizontal hair reading of 1.60 m on the rod, the vertical angle observed was +7 degree 18’.
