Surveying The difference of levels between two stations A and B is to be determined. For best results, the instrument station should be closer to the higher station equidistant from A and B closer to the lower station as far as possible from the line AB closer to the higher station equidistant from A and B closer to the lower station as far as possible from the line AB ANSWER DOWNLOAD EXAMIANS APP
Surveying α and β are the angles subtended by a point of elevation h at their air station with respective plumb points. Photo scale and focal length of the lens being ‘S’ and ‘f’ respectively. Parallax displacement of the point due to relief, is h tan β/S h (tan α - tan β)/S h (tan α + tan β)/S h tan α/S h tan β/S h (tan α - tan β)/S h (tan α + tan β)/S h tan α/S ANSWER DOWNLOAD EXAMIANS APP
