Fly-through videos can be created for project or promotional presentations.

Multibeam echosounder (MBE)

MBE data can be both acquired and modelled in NaviSuite.

Sub-bottom profiler (SBP)

You are able to work with several SEG-Y files in NaviSuite at the same time. When loading the sub-bottom profiling data, the software extracts a rough track that is then taken through a two-step process of extracting a point every 100 metres, and then refined to 3 metres.

EIVA’s data cleaning tool EC-3D

EC-3D supports many automatic and manual data cleaning methods which can be customised and combined for optimal effect. EC-3D is efficient at cleaning data, whether it be 3D or 2D, point clouds or DTMs.

Real-time DTM cleaning

EC-3D cleaning filters can be applied to sonar data in order to clean data in real time as it is being acquired and displayed. The real-time DTM cleaning feature does not modify the acquired data – all the acquired sonar points are available for post-processing after the operation.

EC-3D point cloud cleaning

EC-3D can be used to clean point clouds.

EC-3D features many data cleaning methods

Rather than assuming one method will always work perfectly, with EC-3D, you can use a variety of different methods to identify noise in your data. The many data cleaning methods featured in EC-3D include…

• Histogram spike shooting
• Histogram plane cleaning
• Distance to surface (DTM only)
• Distance to average value
• Distance to mean value
• Distance to nearest point
• Distance to multiple points (median Z)
• Distance to multiple points (median)
• Number of points in a sphere
• Fraction of points in cylinder
• Vertical cluster

You can import and customise the parameters of individual cleaning methods.

Combine cleaning methods

You can run multiple cleaning methods simultaneously, combined in different ways. You can save and load your EC-3D method configurations, so you can use them again on several data sets.

When combining cleaning methods, you can group them as Relative or Absolute. Absolute methods will clean points regardless of any other cleaning method. While Relative methods will clean points in voted-based manner. For example, ‘at least two out of four methods must agree on a point being marked as noise before it is removed’.

Histogram Spike Shooting 

Histogram Spike Shooting can be used to reject or accept DTM points.  

Points are selected if they are inside a circle.

Histogram automatically sets the rejection thresholds (can be manually over-ruled).

Histogram Plane Cleaning

Histogram Plane Cleaning tool can be used to reject or accept DTM points. 

Points are selected if they are inside a corridor, polygon or an existing boundary.

Histogram automatically sets the rejection thresholds (can be manually over-ruled).

Reject & accept points

You can see which points are being rejected or accepted both on a DTM and in a pie chart to visualise the distribution of accepted and rejected points.

Import XYZ files

You can easily model historical data in NaviSuite Kuda and use it for example to plan your survey or compare your results with earlier observations. If you have data in a known format, such as generic ASCII XYZ files, these can be imported as DTMs, point clouds, or TIN models.

Point clouds with RGB and Intensity

By default, point clouds can be visualised as a solid colour or as a depth palette. However, if source files contain RGB or Intensity values, we can choose to colour the point cloud with this information instead.

EC-3D point cloud cleaning

EC-3D can be used to clean point clouds.

Manual cleaning

A selection window or a polygon can be used to manually clean point clouds.

Import LAS files and display as RGB or Intensity

LAS and LAZ files can be imported as DTMs or as point clouds, meaning you can use NaviSuite’s powerful modelling capabilities for validating data in this format. You can also export your model to this format.

Point Cloud Registration (QuickStitch)

If point clouds are misaligned, we can use Point Cloud Registration to align them. We accomplish this by first digitising common features, and then performing a least-squared adjustment that moves one point cloud to another.

Create DTM surface from points (sonar & laser)

DTM surfaces and Point Clouds can be generated at any time from either sonar or laser data. 

Create different DTM surfaces (mean, max, min, etc) and colour modes

Different surface types are generated upon data import and can be accessed at any time.

Light and Palette settings

DTM light and palette settings can be changed at any time.

Visibility Slider

Visibility slider allows users to compare different DTMs quickly.

This enables comparison over time or between different data processing methods.

Difference models

DTMs can be created from the differences between two other existing models.

Volume calculation

Density surface

Density colour mode can be enabled to QC how many points are in each DTM cell.

Custom surface

It is possible to create custom surfaces based upon hard-coded variables or user-configurable equations.

Automatic gap detection

This tool analyses DTMs to identify areas which have no coverage (i.e. contain gaps).

Matchup

Matchup tool can be used to correct for DTM artefacts caused by incorrect ROV XYZ position.

Points are moved based upon differences between two existing lines (source and destination).

Points are moved perpendicular to the destination line.

Rectify

Rectify tool can be used to correct for DTM artefacts caused by incorrect ROV XYZ position.

Points are moved based upon differences between two existing lines (source and destination).

Points are moved perpendicular and along length to the destination line.

If available AutoCAD engineering drawings can also be used.

Rock-placement design

In NaviModel theoretical rock-placement profiles can be designed and visualised inside a 3D environment.

If available AutoCAD engineering drawings can also be used.

Modify lines

Lines can be modified in many different ways.

Line smooth

If required, the entire length of the line can be smoothed in XYZ.

Local smooth

Local smooth tool allows you to concentrate on small line sections that require remedial action.

Convert waypoints to lines

Waypoints can be converted to lines via the ASCii Importer.

Compare lines

Whilst we can always compare lines visually in the Map View window, sometimes it is better to create graphs for comparison.

AUV processing workflow

The first version of the Workflow Manager utilises NaviEdit and NaviModel for a traditional survey data set processing of data from AUV dive. As soon as the data is available, it is automatically loaded into the flow and processed by cleaning data, merging reprocessed AUV track, building DTMs and making sanity checks. This is typically done using the Server version.

NaviSuite Kuda processing workflow

The Workflow Manager desktop version is very well suited for NaviSuite Kuda operations where each file will be processed right after recording, thus enabling reporting and quality control as you go. The Desktop version runs one task at the time – but it is more than fast enough to cope with survey speed.

Execute multiple parallel NaviEdit, NaviModel and 3rd party commands

The more CPU (cores), memory and disk speed you have – the better you utilise the workflow engine. The optimal solution is running a bit fewer processes than the number of cores.

Configurable event types, hierarchy, and properties

Client and company specific event collections can be tailored to the activity undertaken.

During EIVA Days Denmark 2018, we presented a major expansion to the functionality of camera based scanning.

Create events

Events can be created quickly and are automatically placed onto a DTM.

Tablet for fast event creation

Using the eventing tablet view allows for quicker event creation. With the eventing tablet, you can quickly add all events, or customise which events to add with just a few steps.

Create freespan and burial events

Pipe and seabed markers are used to create freespan and burial events.

This means that events and seabed markers always tie-in.

Recalculate events

Events can be recalculated at any time.

Export events

User configurable templates can be created to export events in the format required.

Export nearest image and videos

Images and videos can be exported for each event or for selected events.

Create pipetracker gap events

Pipetracker gap events are created from continuous sections of rejected pipetracker data.

You can also automatically identify and generate DTM gap events for quality control.

Drape images on digitised pipe

Video images can be wrapped around an existing pipe or digitised line in the Map View window.

Play and control video

Digital video acquired in external systems can be played and controlled inside NaviModel.

Synchronise video with track

In NaviModel the track contains the date and time and must be synchronised with the video time to enable videos to play.

Normally the video time and track time are recorded in the same time zone. However sometimes this is not the case and we need the option to change the video / track time so that video will play.

Adjust video hue, brightness, contrast and gamma levels

Hue, brightness, contrast and gamma levels can be adjusted to improve badly lit videos.

Display video images (Waterfall)

Video images can be displayed as a vertical waterfall.

Digitisation of pipe

Pipeline XYZ position can be manually detected by digitising the pipe marker.

Automatically detect pipe position

Pipeline XYZ position can be automatically detected.

Pipe-tracker integration and pipe-tracker statistical tools

Scan-based pipe location

Scan Profile scans contain data points from matching port (red) and starboard (green) systems.

Scan profiles are normally created from acquired Dual Head Scanning Sonar (DHSS) data.

Once created, Scan Profiles can be used by the Profile Analyser.

Profile Analyser

KP Axis view

KP Axis can be used to view and QC events.

Automatic freespan detection

Pipe and seabed markers are used to create freespan and burial events. 

This means that events and seabed markers always tie-in.

Cable route design with bending and slope constraints and cable route vessel placement verification

NaviModel includes a general planning tool for cable and flexible pipe routes. Based on the initial route (imported or drawn), the cable route will be placed on the seabed using the cable characteristics. Operators can then modify the route and in real-time see free-span, side-slopes and curvature. When the final route has been accepted, the system calculates and simulates vessel track using standard catenary data models.
