Adjust Rotate.
The Rotate screen will rotate selected points around a specified point.
This is useful to correct a survey where an incorrect backsight was
used during data collection.
Tap Points… : allows you to select points by
tapping them from a map view.
To/From… : Opens the Point List screen (Page
R-449) where a point list can be created.
Rotation Point: The selected points will be
rotated around the point specified here. (The
coordinates for the rotation point will not
change.)
Simple Angle: when selected, this allows you
to enter the deflection angle to rotate the
selected points.
Old and New Azimuths: when selected, this allows you to enter an
old and new azimuth, which is used to compute the angle to rotate
the selected points.
Note: The choice made from the two options above determines which
fields will be available below.
Rotate: is the angle to rotate the selected points around the Rotation
point.
Old Azimuth / Old Bearing : is a known direction between any two
points in the current job before they are rotated.
New Azimuth / New Bearing : is the direction between the same
two points specified above after the rotation.
