Surveying If v, t and f/H are the ground speed of the aircraft, the shutter speed of the camera and the scale of the photograph respectively, then the amount of image displacement i = v. f/t. H i = v. t. H/f i = v. t. (f/H) i = t. H/v. f i = v. f/t. H i = v. t. H/f i = v. t. (f/H) i = t. H/v. f ANSWER DOWNLOAD EXAMIANS APP
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 as far as possible from the line AB equidistant from A and B closer to the lower station closer to the higher station as far as possible from the line AB equidistant from A and B closer to the lower station ANSWER DOWNLOAD EXAMIANS APP
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)/f f/(H + h) f/(H - h) f/H (H - h)/f f/(H + h) f/(H - h) ANSWER DOWNLOAD EXAMIANS APP
