CARIS Batch Utility : HIPS Processes : Create SIPS Beam Pattern
 

Create SIPS Beam Pattern

Description

The CreateSIPSBeamPattern process creates a beam pattern file that will be used to apply a correction to remove acoustic artifacts from the imagery caused by imperfections in the sonar.

Inputs

One or more HIPS track lines.

Outputs

Updated HIPS track lines and project file.

Command Line Syntax

carisbatch --run CreateSIPSBeamPattern --mosaic-engine <value> [options] <inputs>

Options

The following table describes the parameters available for this process.

Notes

 

Common Options

--mosaic-engine

m

The mosaic engine used to generate the output beam pattern. One of:

SIPS_BACKSCATTER: SIPS Backscatter engine processes multibeam backscatter data referenced by HIPS data

SIPS_SIDESCAN: SIPS Side Scan engine processes side scan data converted into HIPS format

FALSE

This must be explicitly specified.

--beam-pattern-file

b

The path to the beam pattern file.

FALSE

This must be explicitly specified.

MosaicEngine = SIPS_BACKSCATTER Options

--beam-pattern-file-operation

If the beam pattern file selected already exists, sets the file operations on the existing file. One of:

UPDATE: Update - Updates the file with the new line information, can accumulate many lines over many surveys

OVERWRITE: Overwrite - Overwrites the existing file with a new file from the current lines.

The default value is UPDATE.

Cannot be used without --beam-pattern-file set.

FALSE

--s7k-compensated-data

Teledyne Reson s7k format can store Beam Average and Time Series data in raw and compensated intensity datagrams. When this option is set the mosaic will use compensated data from any line containing it and if not found the line will not be used in the mosaic.

FALSE

--local-absorption

A number specifying correction for transmission loss using temperature and salinity values.

<Temperature> - The temperature value in degrees Celsius.

<Salinity> - The salinity value in parts per thousand.

The default values are 8.00 35.00, respectively.

FALSE

--nadir-angle-t1

Set Transducer 1 angles across-track from directly below the transducer (0 degrees) to set how much data is included in the beam pattern file/mosaic.

<Port> - The port side angle from transducer nadir.

<Starboard> - The starboard side angle from transducer nadir.

The default values are 90 90. The valid range is -20 to 100.

FALSE

--nadir-angle-t2

Set Transducer 2 angles across-track from directly below the transducer (0 degrees) to set how much data is included in the beam pattern file/mosaic.

<Port> - The port side angle from transducer nadir.

<Starboard> - The starboard side angle from transducer nadir.

The default values are 90 90. The valid range is -20 to 100.

FALSE

--surface

The path to the surface used to compute the local bottom slope used in the calculations of real incidence angle and ensonified area. The default elevation band will be used.

If not set, the default value is to use the processed bathymetry.

FALSE

MosaicEngine = SIPS_SIDESCAN Options

 

None

Example

To use this command, refer to the following example.

Example

Objective

To remove acoustic artifacts from a HIPS track line.

Description

Command Line Syntax

The mosaic engine to use is SIPS_BACKSCATTER.

--mosaic-engine SIPS_BACKSCATTER

The beam pattern file operation is OVERWRITE.

--beam-pattern-file-operation OVERWRITE

The input HIPS track line file is named input.hips is located at C:\temp\input\. The HIPS file URI filters for the vessel named “sample” and the day 2000-001

C:\temp\input\

The output beam pattern file is named outputBeamPattern.bbp and is located at C:\Temp\

C:\Temp\outputBeamPattern.bbp

Command Line

carisbatch --run CreateSIPSBeamPattern --mosaic-engine SIPS_BACKSCATTER --beam-pattern-file-operation OVERWRITE file:///C:/temp/input/input.hips?Vessel=sample;Day=2000-001 C:\Temp\outputBeamPattern.bbp

Outcome

A beam pattern file is created.
