The angle α is equal to
Which of the following statements about photogrammetric surveying is correct?
Consider the following statements associated with triangulation survey
1. In triangulation survey unknown distances between stations are determined using tacheometric relations.
2. The triangulation station at which astronomical observations are made for azimuths are called Laplace stations
3. In tertiary triangulation, the length of the sides is in the range of 10 to 25 km
4. The length of the base line in primary triangulation is 8 to 12 km
Of these statements
1. In triangulation survey unknown distances between stations are determined using tacheometric relations.
2. The triangulation station at which astronomical observations are made for azimuths are called Laplace stations
3. In tertiary triangulation, the length of the sides is in the range of 10 to 25 km
4. The length of the base line in primary triangulation is 8 to 12 km
Given that for a triangulation survey
D = distance in km
h = the visible horizon from a station of known elevation above the datum (in metres) if there is no obstruction due to intervening ground, then h is equal to
D = distance in km
h = the visible horizon from a station of known elevation above the datum (in metres) if there is no obstruction due to intervening ground, then h is equal to
The sun’s declination remains north in the period between
