2

•  Enter the Average Speed of Sound in to the Sounder Suite Software •  Enter a Draft in to the Sounder Suite Software (measurement from the face of

the transducer to the water line) •  Make Sure the Transducers are Turned on in the Sounder Suite Software and

Enter Hypack Survey in Hypack

• Begin Data Collection!

• Create Your Project • Assign Proper Geodesy • Measure Vessel Offsets to Reference Point. Insert Offsets

Properly in to the Software • Load Files Related to the Survey • Create a Line file which runs Perpendicular to the Area. Line

Spacing Dependent on Level Accuracy Needed and Distance of Survey

• QA Procedure • Open Hypack Survey and Begin Data Collection

4

•  GPS Configurator

• Load All Survey Related Files • Create Line File for Survey Area • QA Procedure

•  Check in to Known Monument with GPS 1 Receiver and Antenna •  Shoot in Water Surface Elevation (WSE) with RTK Rover •  Calculate Final Elevation •  Conduct a Barcheck at the Beginning and End of Survey •  Measure GPS 1 Vertical •  Once Survey is Complete Conduct Manual Polings

• Shoot Water Surface Elevation (will be used to calculate final elevation)

5

• Measure / Verify GPS 1 Vertical Offset

•  Turn on Vessel and Computer •  Make sure all Necessary Programs are Running Properly and Fixed RTK is Coming in

to Hypack

•  Conduct a Speed of Sound Cast and Enter the Average Value in to the Sounder Suite Software

•  Calculate Hypack Final Elevation •  Water Surface Elevation •  Manual Depth Measurement at the Transducer •  WSE – Manual = Final Elevation

•  Calculated Final Elevation Should be Very Close to Hypack Final Elevation

6

•  Conduct a Barcheck. A Series of Manual Depth Measurements with a Special Disc at Differing Depth Intervals (5’ – 10’ – 15’) Referenced to the Waters Surface (the operator inside the vessel must enter a draft in the sounder suite software to correctly compare depths

• Head to the Survey Area!

• Collect Cross Lines Before and After Actual Data Collection • Check Survey Over to Make Sure all Necessary Data has

been Collected • Conduct Polings within the Survey Area Upon Completion (3

Per Area or one per hour) • Shoot the Water Surface Elevation Upon Survey Completion • Tie in to a Known Monument Upon Survey Completion
