Civil Engineering :: Surveying
- The slotted template method
- When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is
- The length of a parallel of λ latitude between two meridians is equal to difference in longitudes multiplied by
- The hour angle of the heavenly body for Greenwich meridian equals the hour angle of the body for any other meridian + longitude:
- Which of the following is not used in measuring perpendicular offsets ?
- The nearest star is so far away from the earth that the directions to it from two diametrically opposite points on the earth differs less than
- Right ascension of a heavenly body is its equatorial angular distance measured
- 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
- The method of surveying by triangulation was first introduced by the Dutchman Snell in
- The rise and fall method
