In order to compute the localization rotation, you need a known
geodetic coordinate system for reference. Use this function to set the
localization coordinate system parallel to a selected mapping plane
Note: Survey Pro versions prior to 3.5 allowed users to calculate
rotation using either a known mapping plane, or relative to the first
base setup. This function is now used only to calculate orientation
from a known mapping plane. Older jobs that had orientation
relative to the first base were automatically converted into a
localization solution when first opened with Survey Pro 3.5.
Localization Calculator – Rotation – Details
Projection: displays the current mapping plane
selected.
&DOF 5RWDWLRQ ! : calculates the rotation and
opens the results screen.
Localization Calculator – Rotation – Results
Convergence : displays the rotation from geodetic
north to grid north of the selected mapping plane.
Rotation : displays the rotation from grid north to
geodetic north of the selected mapping plane.
This is the value used by the localization
solution.
$FFHSW : returns you to the Localization
Calculator screen (Page R-51 ) and enters the
computed rotation factor into the
Rotation field
for you.
