Figure 6. Reposition point cloud data wizard, Instrument resection calculation
In the upper table of the window, the
control points
from the positioning information are
listed. Switch on/off control points or edit control point IDs to adjust the resection calculation.
The following columns are available:
Use
Activate to use this control point for resection calculation.
Control point Id
ID of the control point (edit if the name from the positioning infor-
mation does not match the control points stored in this project).
Any control point defined in the project may be used.
Easting
Easting value of the control point used for resection calculation
(according to selected date and time in step 1).
Northing
Northing value of the control point used for resection calculation
(according to selected date and time in step 1).
Height
Height value of the control point used for resection calculation
(according to selected date and time in step 1).
Date and time
Date and time of the control point coordinate used from the
Con-
trol points
editors of this project.
dE
Residual of Easting coordinate after resection calculation.
dN
Residual of Northing coordinate after resection calculation.
dH
Residual of Height coordinate after resection calculation.
Calculation status
The calculation status column provides information about the
control point.
In the lower table of the window, the old and new parameters from the
instrument posi-
tioning information
are listed. The following columns are available:
Old value
Parameter value of the original instrument position.
New value
Parameter value of the recalculated instrument position.
Delta
Difference between the new and the old parameter value.
Accuracy (1 sigma)
Accuracy derived from the resection calculation.
Calculation status
The calculation status column provides information about the pa-
rameter. If the accuracies are within the required tolerance, the
status is
Ok
