6ROYH ! : computes the horizontal localization parameters using the

entered scale, rotation, and base station local coordinates.

Localization Calculator – Scale

Note: This function is no longer necessary with Survey Pro versions
3.5 and later. The new localization solution sets the origin scale of the
reference stereographic mapping plane based on ground height. This
screen was left in to explain scale factor to users who previously used
this work flow.

8VH 6FDOH : returns to the Localization Calculator screen with a

scale factor of 1.0.

Localization Calculator – Rotation

6XUYH\ 3URMHFWLRQ +RUL]RQWDO 6ROYH /RFDOL]DWLRQ &DOF 5RWDWLRQ

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.
