enable the scale factor edit field and enter any other scale factor.
Ground Coordinates - Location
The Ground Coordinates Location screen is used to define the local
ground coordinate of the origin point. This coordinate will be used to
calculate an offset from the mapping plane grid coordinates so that
you can separate the grid and ground coordinates to make them
recognizable. This screen is used when you select either Key in
coordinates to define origin
or Pick point to define origin on the first
page.
Reference Point Location (Grid)
: displays the
local northing and easting of the ground origin.
Desired Local Ground Coordinate
: is the
desired local northing and easting coordinate of
the ground origin.
Ground Coordinates - Results
The Ground Coordinates Results screen is used
to preview the values to be used for the ground
coordinate system. This screen displays the
parameters for the ground coordinate system.
If the origin was set to use either Key in
coordinates to define origin
or Pick point to define
origin
on the first page, the values on this page
are calculated from the parameters entered in
the wizard. If the origin was set at the
Mapping plane origin
, then you need to enter
the scale and offsets in the edit fields on this
page.
Ground Offsets
: displays the shift applied to the mapping plane
coordinates to get the desired local ground coordinate at the selected
origin.
Scale
: displays the ground scale factor.
