MSTC Refresher 59: Elevation by Tacheometry with Correction due to Earth's Curvature and Correction

The slope distance and zenith angle between points A and B were observed with a total station instrument as 9585.26 ft and 81⁰42’20’’ respectively. The HI and rod readings “r” were equal. If the elevation of A is 1238.42 ft, compute the elevation of B. Consider the effect of curvature and refraction correction. Hcr = 0.026 M2 where M is in thousands of feet. [NOV 2019] A. 2567.81 ft C. 2623.04 ft B. 2451.67 ft D. 2869.24 ft Thanks for watching! Comment for questions and suggestions for future lecture in this series.
