11.7 Area
The Area function enables you to
calculate an area based upon points
in the database. The area segments
may be defined as lines or arcs. The
nodes along the perimeter of the area
must be defined clockwise.
In order to use the area function, local
grid coordinates must be available i.e.
a local coordinate system must be
defined.
Select Area from the APPLICATION
menu.
Job - Change the current Job if
necessary.
Area - Select between defining a New
Area or modify the Last Area. By
default the last area definition will
always be retained allowing you to
modify it.
Change Log File to YES and enter a
File Name if you want to generate a
log file of the area calculation. The file
will be written in the \LOG
subdirectory of the PC card or
internal memory.
Press CONT (F1) will bring you to the
Create Area screen.
To define the segments of a new area
or to add additional segments to an
already existing area press NEW
(F2). Select the points from the list
and press ADD (F2) after each Node
(point) or click ARC (F3) to define an
arc. Arcs can be defined by two
points and a radius or by three points.
Alter-natively you may press NEWOC
(F5) to measure new points. When all
segments of the area are defined
press CONT (F3).
To modify the Id of a Node (point) or
to change the arc definitions set the
focus on that segment and press
EDIT (F3).
