NaviModel offers high-performance digital terrain models in 2D and 3D and high-tech tools for model analyses and manipulations.

This includes carrying out comparison over time by visualising the development between different datasets from the same site, acquired at different points in time – what we call 4D.

NaviModel comes in three variants:

With the NaviModel Producer variant, you get the complete software solution comprising all the features of NaviModel for data processing, cleaning, modelling and reporting.


'I find NaviModel an excellent tool for producing high quality images for my work and publications. I am impressed with the simple interface which makes working with point clouds and digital terrain models very straightforward.'

    Shipwrecks

    NaviModel is often used for modelling shipwrecks, due to its powerful 3D modelling and visualisation capabilities, as well as precise positioning.

    Learn how NaviModel was used for studying WWII shipwrecks down to the millimetre

    In a project using NaviSuite to pan and document a shipwreck removal, our software ‘provided tools that guaranteed a difficult process was made easy and intuitive, enabling fast analysis of data just a few hours after it was collected' said Technical Director Thomaz Tessler, TESSEC Engineering and Maritime Services.

    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.

    EC-3D DTM

    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 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.

    EC-3D Automated

    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’.

    EC-3D data cleaning votes relative methods

    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).

    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.

    Import XYZ files

    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.

    Point clouds with RGB and Intensity

    EC-3D point cloud cleaning

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

    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.

    Manual cleaning

    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.

    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.

    AUV processing workflow

    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.

    NaviSuite Kuda processing workflow

    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.

    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.
