Surveying The scale of a vertical photograph of focal length ‘f’ taken from height of ‘H’ metres above M.S.L., at a point of reduced level ‘h’, is f/(H + h) (H - h)/f f/H f/(H - h) f/(H + h) (H - h)/f f/H f/(H - h) 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 α - tan β)/S h tan β/S h tan α/S h (tan α + tan β)/S h (tan α - tan β)/S h tan β/S h tan α/S h (tan α + tan β)/S ANSWER DOWNLOAD EXAMIANS APP
