Figure 8.11
Ordered vector redundancy.
(Permission ASCE.)
Figure 8.12 indicates that long vectors have large redundancy numbers. The shapes
in this figure suggest that it might be possible to identify vectors that can be deleted
from the adjustment without affecting the strength of the solution. The steep slope
suggests that the assembly of short baselines determines the shape of the network.
Mixing short and long baselines is useful only if long baselines have been deter-
m
ined with an accuracy comparable to that of shorter lines. This can possibly be
