Creating a New Alignment
An alignment is a set of data that can be used to describe and determine the
exact location of a road centerline. It describes the whole road in terms of
elements of the road, including starting point, straight line, curve and spiral.
Create horizontal and vertical road alignment files with the basic field software
and upload them onto the instrument.
Alternatively, horizontal and vertical road alignments can be created onboard
the instrument.
