D.2 Warnings
Appendix D Error and Warning Messages
All messages in this section are simply warnings or informational messages. They do not
cause an adjustment to terminate. Carefully review any warnings to determine whether
any data revisions need be made on not.
Duplicate Sideshot Name
The program found a sideshot data line whose sideshot name was previously used by a
prior sideshot data line. Since sideshot points are independently computed one by one
after the adjustment has completed, it makes no difference what the names are or
whether they are repeated. However, for those wishing to keep all points unique in the
resulting coordinate files, this message offers a warning along with line numbers of the
data lines having the repeated names.
Excessive Scale Factor
You have entered a scale factor greater than 1.10 or less than 0.90.
Inline SCALE Option Ignored in Grid Coordinate System
Inline SCALE Option Ignored when Reducing to Common Datum
You have entered an inline scale factor which is being ignored because the network is
being run in a “grid” coordinate system which calculates scale independently. Also when
running in a “local” coordinate system, the inline scale factor line is ignored when the
you are reducing to a common elevation – only the elevations and earth radius is
considered.
Network Has No Fixed XY Stations
Network Has No Fixed Z Stations
In a 2D or 3D adjustment, you should have at least one station that has fixed horizontal
coordinates. In addition, in a 3D adjustment, at least one station should have a fixed
elevation. Partially fixed coordinates (i.e. those entered with standard deviations) in a
network will often provide the required amount of fixity to allow the network to
successfully solve. Therefore this is only a warning, not necessarily an error. However,
be aware that if components of controlling coordinates have almost no fixity, or no
fixity, the adjustment may fail with a “Geometric Weakness” or “Singularity” errors –
see last section “Errors” for more details.
Network Station Name Reused as One of More Sideshot Stations: xxx
The program found a main network station data line whose station name was used also
by one or more sideshots. Since sideshot points are independently computed one by one
after the adjustment has completed, it makes no difference it sideshot names are the same
as main station names. However, for those wishing to keep all points unique in the
resulting coordinate files, this message offers a warning so that you can search out these
sideshots and change their names if desired.
