Stake out roads
To stake out the alignment, you must first define the alignment type.
You can define the horizontal alignment in two ways:
• Create it in the computer using the data communication software provided with the instrument.
• Manually enter it on the instrument in the Roads menu.
It is not necessary to define the vertical alignment data, unless it is required to compute cut and fill.
The definition method is similar to that of horizontal alignment. Rules of alignment stake-out data
are as follows:
• Offset left: Horizontal distance between the offset point left and the center line.
