11.6 COGO
The COGO functions enable you to
calculate new points using existing
data. This existing data may be
existing coordinates of points, existing
known distances or existing known
angles. Instead of using existing
points from the Job database, points
can be measured on the spot and
used for computation.
In order to use the COGO functions
local grid coordinates must be
available i.e. a local coordinate
system must be defined. Only the
COGO function ‘Inverse’ can also
handle coordinate systems that would
not allow the computation of grid
coordinates.
Select COGO from the APPLICA-
TION menu.
Job - Change the current Job if
necessary.
Change Log File to YES and enter a
File Name if you want to generate a
log file of all the calculations. The file
will be written in the \LOG
subdirectory of the PC card or internal
memory.
Use Offset - Enables you to activate
an additional entry field for a parallel
offset whenever a line is to be de-
fined.
Use Brg. - Enables you to enter and
display bearings in the four quadrants
NorthEast, SouthEast, SouthWest
and NorthWest. If this option is set to
YES and a bearing needs to be
entered the function key QUAD (F6)
enables you to switch between the
quadrants.
Press CONT (F1) will bring you to the
COGO menu.
