1. TARGETS IN SURVEY
HYPACK 2016

2. Targets: What’s a Target?
A Target must have:
X-Y Position
A ‘Target’ can have:
Name
Depth
Associated GeoTIF
Offset information
Distance
Bearing
You can make targets:
By pressing ‘F5’ in SURVEY.
By double-clicking in SURVEY’s Area Map window.
Using the Target Editor.
Marking Targets in SBMAX, MBMAX, HYSWEEP SURVEY or SIDESCAN SURVEY.
Marking Targets in the Sub-Bottom Device Window.

3. Targets: Old Style versus Alarm Targets
Default style targets (radius circles about the marker)
Alarm style targets with name, distance to vessel and bearing from vessel to target.
Switch on-the-fly between the Default and Alarm target displays by going to the Targets – Parameters menu in HYPACK SURVEY.

TGT dE & dN:
Difference in Easting and Northing (Target – Vessel)
TGT Fwd & Stbd:
Distance TGT is Forward & Starboard
TGT Name:
Name of current active target
TGT Time:
Time the vessel would cross over the target, based on the current speed.
TGT Speed:
Speed to travel to cross over the target at the time specified as the target name.

8. Water’s Edge Target: (F7) – Off-line
Water’s Edge targets are used to mark the location of the riverbanks.
While Status = ‘Not Logging’
Move your boat close to the bank.
Press ‘F7’ and enter the estimated distance to the shoreline from the tracking point.
SURVEY calculates the X-Y of the shoreline point.
When you turn and go ‘On- Line’, SURVEY saves the shoreline point as the 1st record in the data file with a depth of 0.0.
Estimated distance from transducer to shoreline X
Planned Line
Shoreline

9. Water’s Edge Target: (F7) – On-Line
Status = ‘Logging’
As you near the far bank:
Press the F7 key.
Enter the distance to the bank (from the tracking point).
SURVEY computes the X-Y of the shoreline point and saves it as the last record in the data file.
SURVEY then closes the file and moves to the next line. X
Planned Line
Estimated distance from transducer to shoreline
Shoreline

10. Water’s Edge in SURVEY
If you’re working with Water’s Edge targets in SURVEY, it’s best to go to the Navigation Parameters and set the Start line gate = 0.0
Trust me on this one.

11. Water’s Edge Results: in SINGLE BEAM EDITOR: Dots
Notice the single points at the depth of 0.0 located at the start and end of line. (I didn’t add any tide correction, so they are still at 0.0.)

12. Water’s Edge: Results in SINGLE BEAM EDITOR: Lines
This is what the profile will look like if you connect the sounding points with line segments. Don’t use this for volumes!
