Solve Localization – Residuals
The Solve Localization Residuals screen is used to display the
residuals from the least squares solution, and to change your control
point selections and re-solve the adjustment if desired.
Solutions
: The box for horizontal and vertical solution
will display the root mean squared results. If the
solution is from a least squares calculation with
residuals, the RMS values are from the residuals of each
point used in the calculation. If the solution is unique
(minimum number of control points or fixed horizontal
scale), the RMS values are from the misclosures of each
point not used in the calculation.
RMS 3D
: displays the 3D RMS calculated from the
square root of the horizontal RMS squared plus the
vertical RMS squared.
Largest H Error
: displays the name of the point with the
largest horizontal error (if a horizontal solution was
calculated).
A point list of all control points is displayed along with
the residual or misclosure for each point (depending on least squares
solution or unique solution). You can change the points used in the
solution and re-solve on this page to display the new residuals or
misclosures.
< Back : returns to the Solve Localization – Control Points screen.
Solve > : is displayed when the point list has changed. Tapping
solve will recalculate the parameters and display new residuals or
misclosures for the control point list.
Next > : advances to the Solve Localization – Results screen.
Solve Localization – Manual Parameters
The Solve Localization Manual Parameters screen is used to input
localization horizontal and vertical parameters by hand. This can be
done to copy a localization solution between data collectors in the
field, or to recreate a localization solution from a raw data printout.
