Appendix D Error and Warning Messages<br />

One or more points were found having ZERO elevation while running in<br />

non-local coordinate system. This may cause erroneous scaling! Check<br />

your entered elevations, or your project elevation if running 2D.<br />

When running adjustments in “grid” systems, all stations should have real elevations or<br />

at least a real project elevation when running in 2D. Check your elevations, or if running<br />

in 2D, check to make sure your “project elevation” is not set to zero - unless of course<br />

your project really is right at sea level.<br />

Only One Fixed Station and No Orientation Constraint<br />

If you have only one fixed station in the network, you should have at least one fixed<br />

azimuth or bearing to provide orientation. Sometimes a partially fixed bearing or azimuth<br />

(or a partially fixed station) will provide the orientation required to allow the network to<br />

successfully solve. Therefore this is only a warning, not necessarily an error.<br />

Only One Fixed XY Station and No Distances<br />

If you have only one fixed station in the network, you need at least one fixed distance to<br />

provide scale. Sometimes a partially fixed distance (or a partially fixed station) will<br />

provide the scale required to allow the network to successfully solve. Therefore this is<br />

only a warning, not necessarily an error<br />

Two Stations Have the Same 2D Estimated Coordinates<br />

An observation is found having its two ends defined by two stations that have the same<br />

approximate coordinates. <strong>STAR*NET</strong> changes the coordinates on one slightly (as long<br />

as it is not fixed) and continues processing.<br />

Vertical Observations Ignored in 2D Adj Using 3D Mode<br />

Any single observation “V” line entered as 3D data is ignored in a 2D adjustment. Also<br />

any elevation difference data value entered as 3D data on a “T”, “M”, “DM” or “DV”<br />

line is ignored in a 2D adjustment. The message is only published once upon the first<br />

encounter of a data line having the ignored data. This is not an error, only a reminder that<br />

some data entered by you is not being used for any purpose in the adjustment.<br />
