Localization Calculator

This sub section describes a feature available only in Ground – TDS
Localization

mode.

The Localization Calculator is used to enter the

horizontal localization parameters using the pre-Survey
Pro 3.5 procedure.

Scale

: is where you enter the scale factor used to

transform distances on the localization mapping plane to
your project coordinate system.

Note: Using versions of Survey Pro after 3.5, the
localization scale should be very close to 1.0. See the

user's manual for a more detailed explanation of
localization scale values.

Rotation

: is where you enter the rotation angle used to

transform the orientation of the localization mapping

plane to your grid orientation of your project.

Calc. Scale : opens the Localization Calculator screen where the

horizontal scale factor is explained.

Calc. Rotation : opens the Localization Calculator screen where the

rotation can set parallel to a mapping plane selected from the
database.

Base Station Local Coordinate

: are the local plane coordinates of the

base. If you set up on a new base point, these fields are blank and
you need to occupy one control point to calculate the base station local

coordinates.

Occupy Control : opens the Control Points screen (Page R-197), where

you select a control point to occupy. When you are done, the base

local coordinate is calculated using your entered scale and rotation.

Solve > : computes the horizontal localization parameters using the

entered scale, rotation, and base station local coordinates.
