When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is
-
The distance between the minor control point and the principal point should be equal to

The Polaris describes a small circle round the pole whose radius is approximately
-
The plane at right angle to the zenith-nadir line and passing through the centre of the earth, is called

A.
The plane passing through the perspective centre of a stereo pair and a ground point, is known as basal plane
|
|
B.
Each pair of image points on stereo pair have their own basal plane
|
|
C.
Relative orienation means reconstructing the basal plane
|
|
D.
Relative orientation of the model is achieved only when five points within the model are cleared of Y-parallax
|
|
E.
All the above.
