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 following data was recorded as observed for points B & C. (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?

Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.
