Correcting for TidesCorrecting for Tides

Tide Corrections: Using a Tide Correction File:

Make a Tide Correction file (*.TID) in the MANUAL TIDES program.

Enter the name of your file RTK Tides:

No entry is needed. Set up RTK Tide parameters in

Advanced tab of Read Parameters window.

Manual tides entered during SURVEY:

No entry is needed. Specify ‘Manual Entry in

Survey’ as Tide Device in Selection tab of Read Parameters

Telemetry Tides: No entry is needed. Specify telemetry tide device

as Tide Device in Selection tab of Read Parameters.

Correcting for Sound VelocityCorrecting for Sound Velocity

Sound Velocity Corrections Calibrated sounder with a bar

check: No correction file is

needed. Using a velocity probe:

Create a Sound Velocity Correction file (*.VEL) in the SOUND VELOCITY program.

Enter the name of your correction file.

Using fixed corrections at different depths: Go to TOOLS – SOUND

VELOCITY ADJUSTMENT

Separate corrections can be computed for the high and low frequency depth values.• Use Depth 1 computes an SV correction for both frequencies, using just the high frequency.• Use Depth 2 computes an SV correction for both frequencies, using just the low frequency.• Use Both, computes separate SV corrections, using the depths of the high and low frequency.

Set ‘Tide’ to ‘Manual Entry in SURVEY’ To read Tide values that were manually entered during data collection.

‘Snap to Line’:Moves soundings so they

fall on the planned line. Pretty, but….. Dangerous

Divides each survey line into ‘Blocks’.

Blocks can be created by:• Time (Seconds)• Distance (ft or m)• # of Depths

Loads one depth from each block into the spreadsheet.• Min, Max, 1st in Block,

Average To thin your data, it is

preferable to use one of the Sounding Selection routines AFTER you edit your data.

Select ‘Yes, Except Events’ to protect the location of your event marks.

Read Parameters: Read Parameters: GPS Pre-Filter WindowGPS Pre-Filter Window

Used to pre-filter positions and/or RTK Tides.

If Quality of GPS position is less than specified:• Position is not used

(top section)• RTK Tide is not

computed for point (bottom section)

• When positions are deleted from interior of line, new positions are interpolated and depths are not lost. • When positions are deleted from the ends of a line, depth data is lost.

Read Parameters: Read Parameters: Advanced WindowAdvanced Window

RTK Tides: Enable RTK Tides and Select a

Method Average Tide (preferred) Averaging period = 5 wave periods

(in secs.) Recalculate allows you to fix

problems due to bad configurations.

MRU Apply Heave:

That’s why you bought it. Apply Pitch and Roll Corrections:

Re-computes position of transducer using pitch and roll data.

Remove Heave Drift: Tries to re-center the heave about

the ‘0’. POSPac Adjustments & Post-

Processed GPS Corrections Allows you to adjust positions with

post-processed *.OUT and comma-separated-value files.

Heave values can drift ‘off-center’ due to rapid accelerations or changes of direction.

Read Parameters: Read Parameters: Advanced Window: Steer Sounding BeamAdvanced Window: Steer Sounding Beam

DD’

X,YX’,Y’

The position of the sounding is based upon the center of your transducer beam.

‘Steer Sounding Beam’ computes a new location for the center of your transducer beam, based on the pitch and roll values, and the beam width of your transducer.

D’ = cos(pitch)*cos(roll)*D.

Echogram Window: Used to display the acoustic data for each ping from network-capable echosounders. You’ll need a network echosounder!

Heave Window: Displays raw heave values. Examine each line for heave drift!

Tide and Draft Window: Shows tide corrections. Very useful for RTK tides! Allows you to cut out short periods where you have lost RTK fixed.
