below. Depending on timing, and access points to the target sampling area, the field crew would occasionally layout a set of points along coordinates in one direction and then sample them in reverse order.

At each one-meter interval along the transact, a "laser point bar" was situated parallel to, ajid approximately 4.5 to s.0 feet vertically above the ground surface.
