Method Options:
 North-South, East-West
: When total stations are used, the direction to go in stakeout can be North-South,
East-West. For instance, the program might advise, "North 3.582, East 1.917." This method is better suited to GPS
work and is subject to having a sense, in the field, of the north direction.
 In-Out, Left-Right
: Nearly all surveyors choose this method. If you are staking a point located 100 meters from
the instrument, and take a measurement at 97 meters, the program will respond, “Out 3”. If the In-Out, Left-Right
method is selected, then the Ref. Object and Directions From options become available to further define left-right.
The Ref. Object box allows you to choose a stationary point by which the directions will be referenced. This point
can be either the instrument or a known point. If Ref. Object is set as instrument, then left is defined as left of the
line between the instrument and the rod. Likewise, if Ref. Object is point then left is defiined as left of the line
between the point and the rod. The second option, Directions From, allows you to decide whether the directions
are relative to the stationary point selected in Ref. Object or to the moving Rod.
 Direction to Point—Azimuth, Distance
: This directs you to the point for stakeout by the total distance and the
azimuth, in either the 360 degree circle or a 400 degree circle if configured to grads. The Use Horizontal Clock
system
option converts the 360 (or 400) circle into a 12-hour circle with 60 minutes per hour, and is used in certain
military applications. North is 12 o’clock.
 CL In-Out, Forward-Back if Alignment available
: This option overrides the settings above, and if the stakeout
involves a centerline, the program will direct the user by distance in to or out from the centerline and forward or
back along the centerline.

This tab allows the user to define how the software will handle angle sets, reciprocals, and direct and reverse.
