Surveying While making astronomical observations, the observer is mainly concerned with The direction of the poles of the celestial sphere All listed here The direction of the star from the instrument The direction of the vertical, the axis of rotation of the instrument The direction of the poles of the celestial sphere All listed here The direction of the star from the instrument The direction of the vertical, the axis of rotation of the instrument ANSWER DOWNLOAD EXAMIANS APP
Surveying If ‘δ’ is the declination of the Polaris and ‘λ’ is the latitude of the place, the azimuth of the Polaris, is cos δ/cos λ sin (90° - δ)/sin (90° - λ) cos (90° - δ)/cos (90° - λ) tan (90° + δ)/tan (90° + λ) cos δ/cos λ sin (90° - δ)/sin (90° - λ) cos (90° - δ)/cos (90° - λ) tan (90° + δ)/tan (90° + λ) ANSWER DOWNLOAD EXAMIANS APP
