26. CROSS SECTION SURVEY
206
When "Right" or "Left -> Right" selected
Pattern 1: From right-most point to left-most point.
Pattern 2: Center point observed first. Then the point immediately to the
right of the center point. Remaining points can then be observed
in any order.
Pattern 3: Method using 2 prisms. Center point observed first followed by
the point immediately to the right. Subsequent observations can
be in whatever order is the most efficient for operation with 2
prisms.
When "Left -> Right" or "Right -> Left"
selected, observation of a subsequent
cross-section can be switched
automatically to the opposite direction
upon completion of the previous cross-
section observation. This method
minimizes the walking distance to the
next starting point when measuring
multiple cross-sections.
