Data Collection

When collecting a point offset, it is important to input the offset
data before occupying the auxiliary point.
• Azimuth Distance: Enter Azimuth, Distance and Delta
Height before occupying the point.
• Azimuth Azimuth: Enter Azimuth and Delta Ht for 1st
position from Aux Pt. A; then repeat for PT B.
• Distance Distance: Enter Distance and Delta Ht for 1st
position from Aux Pt A; repeat for position B and choose
the solution method (i.e. Left or Right)
Remember: Because two solutions exist for a double
distance intersections, the user must tell the
software on what side of point A-B the offset
point lies.
• Backwards Azimuth and Distance: Useful when locating
a point by direct occupation when no GPS exists. The BAD
works by providing an azimuth and distance to a previously
located point. The calculation then reverses the course
and distance.
2.4.4 Line and Area Collection
Unlike point collection, lines and areas offer multiple methods
of collection; noding (i.e. collecting by vertex), streaming by
time or distance, locating nodes by point offsets, creating
linear offsets to either side of the collected line, pasting a node
from the clipboard, and nesting additional features. Because
the Start/Stop button is necessary to both stop in noding and
pause in streaming, features must be saved by the Done
button or the Save Feature in the context menu.

Tip: When escaping the feature collection, a dialog will
allow the user to save or discard the current feature.
