Ground Coordinates - Key In Origin
Survey Projection Mapping Plane Ground… Next > .
The Ground Coordinates Key In Origin screen is used to input the
location of the ground coordinates origin. This screen is used when
you select Key in coordinates to define origin on the Setup screen.
Project Location
: is where you enter the local
point from which the ground coordinate scale
factor is to be applied.
Coordinate Type
: is where you select the type
of coordinates to enter. You can use WGS84
geodetic, local geodetic, or grid coordinates.
This choice will affect the fields displayed
below.
North/Latitude:
is where you enter the northing
/ latitude of the local origin.
East/Longitude:
is where you enter the easting / longitude of the local
origin.
Elevation/Height:
is where you enter the vertical coordinate of the
local origin.
Ground Coordinates - Scale
The Ground Coordinates Scale screen is used to compute the scale
factor to convert grid to ground coordinates for the reference height.
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 (Local)
: displays the
local Latitude, Longitude, and Height of the
ground origin point.
Scale Factor
: displays the inverse combined
scale factor for this ground setup. This scale
factor is automatically calculated based on the
local ground origin.
Override scale factor
: is where you can over
ride the scale factor. Check this control to
