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 α - tan β)/S h tan β/S h (tan α + tan β)/S h tan α/S h (tan α - tan β)/S h tan β/S h (tan α + tan β)/S h tan α/S ANSWER DOWNLOAD EXAMIANS APP
