11. Tap the Stake CP > button to continue to
the next screen where the catch points at
the current station can be located. This
screen is identical to the screens used in
the non-road layout slope staking routine.
If you are not familiar with these screens,
refer to Page 153.
12. Once the catch point is staked and stored,
you will return to the screen described
above where the station to stake can be
advanced by the station interval by tapping
the Next Station button and the process can be repeated to stake
the next catch points.
Station Equation
Some alignments will have a specific location where the stationing
changes. One example of when this might occur is where the
alignment you want to stake merges with another alignment and at
the location where they merge, you want to switch to the stationing
used from the other alignment.
The Station Equation screen is used to define
the location on the alignment where the
original stationing, or the Back stationing
changes as well as what the new stationing will
be from that point forward, or the Ahead
stationing.
In most situations, the ahead stationing will
increase as you advance down the road, but you
might also have a situation where the ahead
stationing decreases as you advance forward.
The Forward Direction section of the screen
allows you to configure the station equation
either way.
When staking a road that uses a station equation, all ahead stations
are shown with a (2) after it to differentiate them from the back
stations, such as 11+00 (2). Likewise, when keying in an ahead
