• Control Code
- the control code used for the given point.
• Control Code 2
- the control code used for the given point. The
Control Code 2 has the same functionality as Control Code
.
• Combined Scale Factor
– the scale factor applied to convert grid
distances to ground distances: K
comb= ((Ell.Height +R)/R)/
Mapping Scale), where R- is the mean earth radius.
• Convergence
– the angle between geodetic north and grid north.
• Color
-point color for CAD View. The color can be chosen from
the list. If you set BYCODE or BYLAYER, the color of the point
automatically will be set to the color that was selected for the
point's code or point's layer.
• Point Symbol
– a point symbol for CAD View. The symbol can
be chosen from the list. If you set BYCODE or BYLAYER, the
symbol of the point will be automatically set to the symbol that
was selected for the point's code or the point's layer.
• Geoid Separation
- some constant, which is the characteristic of
the current geoid model and is calculated for the given point. To
get the orthometric height of the point, subtract the value of this
constant from the value of ellipsoidal height. This value is
displayed when the corresponding geoid is selected for this job.
Right-click on a highlighted line to display a pop-up menu. This
menu contains a set of commands that can be divided into two
groups:
common commands for all tabs
of the Tabular View
specific commands for the Points tab
NOTE: If the corresponding geoid file is added to the job and the
geoid covers the area where the job’s points are located, orthometric
heights will be displayed in the Elevation column, when you select
Ground or/and Grid or/and Datum with Elevation coordinate systems
in the Job Configuration window or in the Status Bar. If the
corresponding geoid file is not added to the job or it does not cover
the desired area, the Elevation column will display the ellipsoidal
height for all points of the job.
