Multibeam Survey data command arguments

Syntax

Description

Commands for working with multibeam survey data.

Arguments

import [path filepath] [all]

Import Multibeam Sonar Data to a folder of type Multibeam. If no path argument is specified, the file Multibeam files dialog will be activated for selecting the input files.

path filepath

Specify the full path to the multibeam survey file. Only one filepath can be specified after the path argument, but several path arguments can be specified, if wanted.

all 

Read all points an do not apply the option Filter zero depth values.

pingbeams [index value] [nbeams value]

Create swath of pings one ping in a multibeam survey line. The command will create the dataset in a memory location named ping. To display the points, enter the command mlo ping, and then the poi command. The command is useful to show the geometry of the multibeam swath.

index value

Specify the index for the ping to create the points from. The value is from 1 to number of pings.

nbeams value

Number of beams to display in the swath. The value is from 1 to number of beams.The default value is 15.

Example:

seafloor pingbeams index 50 nbeams 9  # Create the pings, index 50, number of beams 9 
mlo ping                              # Make the points active 
poi col gre                           # Display the points with green colour

seafloor pingbeams index 50 nbeams 9    # Create the pings, index 50, number of beams 9
mlo ping                                # Make the points active
poi col gre                             # Display the points with green colour

pingpoints [swath] [range] [index value]

Create xyz points from one ping in a multibeam survey line. The command will create the dataset in a memory location named ping. To display the points, enter the command mlo ping, and then the poi command. The command is useful any show difference in the calculation of the multibeam points.

index value

Specify the index for the ping to create the points from. The value is from 1 to number of pings.

swath

Create the points from the swath data (the across, along and depth values from the datagram). This is the default option.

range

Create the points from the range data, using the beam range, sound velocity and motion sensors etc.
