Surveying When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is θ = z + δ θ = 180° - (z + δ) θ = δ - z θ = (z + δ) - 180° θ = z + δ θ = 180° - (z + δ) θ = δ - z θ = (z + δ) - 180° 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 α/S 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 ANSWER DOWNLOAD EXAMIANS APP
Surveying Normal tension is that pull which neutralizes the effect due to pull and sag makes the correction due to sag equal to zero is used at the time of standardising the tape makes the correction due to pull equal to zero neutralizes the effect due to pull and sag makes the correction due to sag equal to zero is used at the time of standardising the tape makes the correction due to pull equal to zero ANSWER DOWNLOAD EXAMIANS APP
Surveying The difference of height of two points whose parallax difference is 0.8 mm on a pair of stereo pair taken from a height ‘H’ is 100 m. If mean photo base is 95.2 mm, the flying height is 12,000 m 10,000 m 14,000 m 8,000 m 12,000 m 10,000 m 14,000 m 8,000 m ANSWER DOWNLOAD EXAMIANS APP
