Solve Localization and Detect Blunders
Before this page is opened, the localization is solved using
all the control points, and then the automatic blunder
detection routine runs to detect low quality control points.
If Yes is displayed in the H or V column, it indicates the
corresponding control point will be included in the
horizontal or vertical localization solution, respectively.
This can be toggled between Yes (included) or blank (not
included) by tapping on it. If the blunder detector
detected any poor quality control, it will automatically
turn off that control before this screen opens. See Page R-
288 for more information on evaluating the localization
parameters displayed on this screen.
The possible outcomes of the solve localization and
blunder detection are:
• Green Light: If the localization solved and no
blunders were detected, you will see a green light
and the status line will show the root mean
squared (RMS) error of the horizontal and vertical solution.
• Yellow Warning Triangle: If the localization solved and no
blunders were detected, but some of the points used have a
large residual error, you will see a yellow triangle and the
status line will show the point with the largest horizontal
and/or vertical residual.
• Red Stop Sign: If the localization solved, and blunders were
detected that could not be clearly identified, or if you were
prompted to remove blunders and you said no, then you will
see a red stop sign and the status line will indicate there are
possible blunders in the solution.
• Yellow Arrow: If the localization solved, but the control
points are not spaced far enough apart to run the automatic
blunder detection, then you will see a yellow arrow, and the
