This program enables the easy definition of a line or curve or
spiral as a reference for measurements and stake outs. It
supports chainages (stationing), as well as incremental
stakeouts and offsets.
Before starting road design and stakeout, the job, station, and
orientation should all be set first.
Defining a horizontal alignment
Horizontal alignment consists of the following elements: start point, line, curve and spiral.
To define a horizontal alignment, first input detailed information (Chainage, N, E coordinate) for the
start point.
The serial number and the amount of the present horizontal alignment are displayed on the upper
right corner of the screen.
The start point consists of the start chainage and N, E coordinate of start point. Enter these details,
and press
[REC/ENT]
to display the main line input screen.
The screen displays the current chainage, the azimuth angle of the tangent on the chainage, and the
function keys for establishing new line. The system provides four functions: defining line, curve,
spiral, and point.
Select a function key, enter the detailed information for the chainage and the alignment elements
will be created. Press
[REC/ENT]
to calculate the new chainage and azimuth angle automatically and
return to the alignment definition main menu. You can now define other line types.
