ground. It is automatically opened to provide the option of updating job file points any time you change the coordinate
system definition, such as selecting a new mapping plane zone or switching horizontal projection modes. Finally, it
can be opened by the user from the Survey menu to select and update points with a projection adjustment.
The screens displayed will vary depending on the action that opened the Adjust with Projection wizard. All of the
screens are described below.
Adjust with Projection – Select Points
The Adjust with Projection Select Points screen is used to select points to be adjusted, and how to adjust them. This
screen is only shown when the wizard is opened from the menu.
[To/From…]: Opens the Select Point(s) screen where you can select points by specifying a point range.
[Tap Points…]: Opens a map view where you can select points by tapping them on the screen.
There are two adjustment modes:
Source to Destination Projection: Use this mode when you want to adjust locations in one coordinate system into
locations in another coordinate system. You can choose the source and destination coordinate systems from the
database. This mode has two options:
Adjust all selected points: All eligible points are adjusted. Points with plane only locations will be transformed
into a temporary WGS84 geodetic location using the source coordinate system, and then into a new plane
location using the destination coordinate system. Points with a geodetic location will be transformed into a new
plane location using the destination coordinate system.
Adjust only geodetic points: Only points with geodetic locations will be adjusted. All eligible points with
geodetic locations will be transformed into a new plane location using the destination coordinate system.
Readjust with Current Projection: Use this mode when you want to readjust locations using the current coordinate
system. This mode has two options:
Geodetic to Plane (Hold LLH | Adjust NEE): Use this option to adjust the plane location of selected points
with a geodetic coordinate. The plane location of selected points with a geodetic location will be recalculated
using the current coordinate system set in the job.
Plane to Geodetic (Hold NEE | Adjust LLH): Use this option to adjust or add geodetic locations to all points. The
plane coordinate of all points will be used to calculate geodetic coordinates using the latest projection. Points that have
geodetic coordinates will be updated, points that did not have geodetic coordinates will be set with the latitude,
longitude, and height calculated from the transformation.
Adjust with Projection – Select Source Coordinate System
The Adjust with Projection Select Source Coordinate System screen is used to select the coordinate system of the
current job file points. When the adjustment mode is Readjust with Current Projection, this screen shows the current
coordinate system record details. This screen only shows when the wizard is opened from the menu.
The Select Source Coordinate System screen is almost identical to the Select Coordinate System screen described in
the mapping plane section. The following controls are special to the Adjust with Projection wizard.
Source Projection Record: Select what type of coordinate system record to choose for the source. The options are:
