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.
Sonar and subsea laser data cleaning tools
Clean point data with a plethora of tools: manual or automatic, real-time or post-processing.
Sonar and subsea laser data cleaning
Clean point data with a plethora of manual or automatic tools. Cleaning operations can be applied multiple times to a complete data set or user-defined areas.
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.
Point cloud tools
Create point clouds from sonar and laser systems or from historical XYZ files. Within NaviModel, there are many ways to visualise, edit and optimise point data.
Point cloud features
We can create point clouds from sonar and laser systems or from historical XYZ files. Within NaviModel, there are many ways to visualise, edit and optimise point data.
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.
DTM tools
In NaviSuite Digital Terrain Models (DTMs) can be generated, manipulated, and edited with the help of various tools.

Automatic data processing tool
Save time on data processing by automating your workflow – using NaviSuite Workflow Manager, designed to enable a previously unseen degree of automatic data processing of massive amounts of subsea sensor data.
Automatic processing features
The NaviSuite Workflow Manager tool is designed to enable a previously unseen degree of automatic data processing of massive amounts of subsea sensor data.
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.
Eventing
The many eventing features include auto-calculation of event types and an easy-to-use event tablet view.
