These self-assessment problems accompany the mini course On Datums and Network Design.
Problem 1
In Lab 5:
a) If you were to remove only the distance measurements from the adjustment, would you have a datum problem? If so, what is / are the defect(s)?
b) If you were to remove only the known coordinates of point 1, would you have a datum problem? If so, what is / are the defect(s)?
c) If you were to remove both known points (1 and 2), would you have a datum problem? If so, what is / are the defect(s)?
d) If you were to remove both known points (1 and 2), could you still solve for the misalignment error by itself?

b)
Problem 3
