4.5: Collecting 3D Data
Step 1: Position Antenna
Once in the 3D Collection screen (after pressing the green Start button) you will see a grid layout in the
center of the screen. The grid coordinates are displayed at the bottom left and top right corners of the grid.
The X and Y line lengths appear on the bottom and left side of the grid. At the top of the screen the total
number of lines is displayed along with the number in both the X and Y directions.
The estimated file size for the grid is also displayed at the top. A yellow line and red box appear at your
starting coordinate. Position the center of the antenna over the starting coordinate for your grid. Typically
that will be at (0,0), where the center of the antenna is centered over both the X and Y baseline at the
same time.
Step 2: Begin Collection
Once the antenna is centered over the starting
coordinate press the green Start button. This
initiates data collection of Line 1. Nothing will
happen until you begin to push or pull the
survey wheel. Once the survey wheel starts
moving in a forward direction (or whichever
direction was used during SW calibration) you
will start collecting data and see the yellow line
progress across the screen.
After traveling the distance that you specified
in 3D Setup, the SIR 4000 will automatically
stop collecting data. The file will save and the
system will automatically increment to the next
line.
Orientation – Positioning the Next Line
Forward or Reverse Line Orders:
Move your cart back to the baseline that you started from.
Zigzag Line Order:
Turn your antenna around and position the center over the next line, but going in the
opposite direction.
Start/Stop Buttons
The Start and Stop buttons offer different functions depending upon how long you press them.
Green Start Button:
Long and Short presses both start collection of a single line or continuation of a
paused line when using Add Segment.
Red Stop Button:
Short press ends data collection along a line. Long press saves the grid and exits data
collection.
