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.
