1) 2 points B &C were observed from point A where the instrument was set up at a height of 1.25m. Points B & C are ahead of point A. The surveyor used an internally focusing telescope with a stadia interval factor of 100. The table below shows the data recorded as observed for points B & C. Answer the following. (Show complete figures and solutions) a) What is the stadia constant of the instrument? b) What is the slope distance between the telescope at point A and the rod reading at point B? C) What is the difference in elevation between point B & C? d) What is the slope distance between the ground surface at point B and the ground surface at C? e) What is the elevation of point C if point A is at an elevation of +0316.15m above mean sea level?
