Used to pre-filter positions and/or RTK Tides. Select ‘Yes, Except Events’ to protect the location of your event marks. 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. Blocks can be created by: Time (Seconds) Distance (ft or m) # of Depths Loads one depth from each block into the spreadsheet. Project Area Boat Surveyor Geodesy info from 1st data file. Entries from SURVEY’s Project Information window. Shows: Time and Date of the 1st data file. Dangerous 5Ĭhanging offsets ONLY works when reading in RAW data files! Change the Latency value. ‘Snap to Line’: Moves soundings so they fall on the planned line. Set ‘Tide’ to ‘Manual Entry in SURVEY’ To read Tide values that were manually entered during data collection. Use Both, computes separate SV corrections, using the depths of the high and low frequency. Use Depth 2 computes an SV correction for both frequencies, using just the low frequency.

Use Depth 1 computes an SV correction for both frequencies, using just the high frequency. Separate corrections can be computed for the high and low frequency depth values. After editing your data, run the SOUNDING ADJUSTMENT program. Using fixed corrections at different depths: No entry is needed. Using a velocity probe: Create a Sound Velocity Correction file (*.VEL) in the SOUND VELOCITY program. Sound Velocity Corrections Calibrated sounder with a bar check: No correction file is needed. Manual tides entered during SURVEY: Specify ‘Manual Entry in Survey’ as Tide Device in Selection tab of Read Parameters Telemetry Tides: Specify telemetry tide device as Tide Device in Selection tab of Read Parameters. Set up RTK Tide parameters in Advanced tab of Read Parameters window. Enter the name of your file RTK Tides: No entry is needed. Make a Tide Correction file (*.TID) in the MANUAL TIDES program.
