Combining several hydrographic survey data types during acquisition and post-processing
… through interfacing to high-tech sonars and lasers, thereby reducing costs and the risk of errors

High-quality sensor processing and editing features
… that minimise time spent on post-processing and improve the quality of your bathymetric survey results

Increased precision of data
… through interfacing to standard vessel navigation equipment and the possibility to purchase the EIVA ATTU time-tagging unit as an optional extra

High-performance hydrographic data acquisition and processing in real time
… as the size of data sets is only limited by disc capacity and it is possible to make terrain models on the fly, thereby allowing for better bathymetric survey data quality and fast reporting

Advanced hydrographic sensor data acquisition and processing software

NaviSuite Kuda is the optimal solution for time-efficient, high-quality bathymetric surveys, such as harbour and waterway surveys, as well as construction inspections.

By bundling the NaviSuite features relevant to hydrographic survey operations into a dedicated single-user solution, you get an affordable toolbox without compromising on the quality of its contents or its capacity, as it is only the disc size that sets a limit for the size of data handled by the software.

As NaviSuite Kuda is part of the NaviSuite family, you can easily upgrade your solution should your needs change in terms of licences or features. In other words, you can go from a single-user setup to a large network installation with multiple operators and remote displays without changing software.

NaviSuite Kuda includes hydrographic survey features such as Kalman filtering, tide correction, final georeferencing, 2D/3D/4D analysis tools for volume, distance, difference and quality control, just to mention a few.

These add up to sensor processing and editing capabilities of the highest quality, which ensures that human and sensor errors are corrected throughout the data workflow. The outcome is high-quality bathymetry survey results and time saved during post-processing.

Apply raw data throughout the workflow of your hydrographic surveys

The acquired data can be applied as raw data and combined throughout the acquisition and processing workflow. This means that you save time and are able to create a single end report with all relevant bathymetric/hydrographic survey data included.

The EIVA crew encompasses experienced software engineers and engineers specialising in sensor technology. This means that you get a software solution developed by a highly qualified team of experts who know how to ensure that you benefit the most from the technologies included in your hydrographic survey spread.

Eliminate the need for manufacturer-developed software

The list of sonar types and laser, which NaviSuite Kuda interfaces with, includes multi-beam echo sounders and sidescan sonars to laser scanners. It allows for support of multiple (up to ten) sensor heads at the same time during your hydrographic survey operations and tracking of a towed or remotely operated vehicle via USBL.

Also, more simple solutions such as single beam echo sounders and magnetometers are covered by the more than 500 drivers included in the bundle.

NaviSuite Kuda interfaces to standard navigation equipment (GPS, MRU, INS, etc), allows for S-57 generation (optional extra) and supports SevenCs charts, raster maps such as GeoTIFF files from, for example, satellite images, 2D/3D CAD, GIS objects and export of GISs, printed reports and videos.

Consequently, the need for manufacturer-developed software is eliminated, and you only have to invest in a single software solution for your hydrographic surveys. Moreover, as you are not working with several different solutions and data formats, the risk of errors is vastly reduced.

The acquired data can be applied as raw data and combined throughout the acquisition and processing workflow. This means that you save time and are able to create a single end report with all relevant hydrographic/bathymetric data included.

As NaviSuite Kuda supports standard vessel navigation equipment such as GPSs, motion reference units (MRUs) and INSs, you are ensured a high precision of your data – a very high precision, if desired, by adding the certified EIVA ATTU time-tagging unit as an optional extra to your NaviSuite Kuda setup. The EIVA ATTU offers a time-tagging accuracy better than 50 µSec, which is far superior to what can be obtained through the use of the standard clock of an ordinary computer.

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

Live position of multiple objects

NaviPac Helmsman’s Display 4 (based on the same core as NaviModel) supports display of vehicle data (main vessel, ROV, ROTV, remotes etc) based on the NaviPac data feed. The data can be shown graphically in multiple map views.

AIS tracks

All variants of NaviPac supports integration with AIS receivers. The data is read into NaviPac and can be shown in a dedicated AIS window and overlaid in the HMD. We perform an even read and utilise vessel dimension information.

Display north-up, heading-up, route-up

Each Map View can be designed and controlled individually when it comes to content, overlays and layout. Map Views can be 2D, 3D or side-views, and orientation can be user defined, north-up, vehicle up or line up.

Manual waypoint drawing

NaviPac supports a series of runline and waypoint formats including our own RLX/WPT format, ad generic ASCII readers. You can also draw lines and points directly in the Map View.

Various runline patterns (parallel, cross, star)

You can inherit multiple lines based on the base line defined, such as parallel or cross lines to get an optimal route plan.

Vehicle control panel for multiple vehicle runlines and display DOL

Assignment of lines and waypoints are handled through the dedicated Vehicle Control view, as you may control multiple vehicles simultaneously. Each controlled vehicle will be available as distance offline indicator (DOL/DCC) and various runline information (along line, target ETA etc.).

Auto-coverage runlines based on sonar

HMD 4 includes a tool for automated runline generation for MBE site surveys. Initially the surveyor defines the first runline, and then HMD will the continuously calculate the outer limit for the line based on coverage and density requirements, and thus automatically calculate the next line. This tool is very suitable e.g., for vessel mounted solution for NaviSuite Kuda or for ASV/USV operations.

Automatic run-in for next runline

When using the auto-coverage tool you may also introduce the automatic run-in. The system will be based on vessel turn capabilities and calculate the shortest route to the next line.

Distance to waypoint

Waypoints are handled in a similar manner to runlines, as assignment of the waypoint is done in the Vehicle Control View. Hereafter, an artificial runline is created from the vehicle to the point and NaviPac monitors the range/bearing to the destination. and can a,.o. feed that into autopilots and DP systems.

Multi-object live range/bearing

In the HMD you may pair any live vehicle (e.g. Vessel and ROV) and monitor the range/bearings between them for online display as live data and range information on Map Views.

Auto-pilot (NMEA) control

When using runlines and waypoints you may connect NaviPac to autopilot systems using e.g., standard NMEA formats and pass cross-track error and destination waypoints on to the equipment.

DataUnits

NaviPac 4.2 supports use of other data units in addition to metric. The unit is selected in the project settings and all definition fields are then assumed to be in the selected data unit. 
HMD will follow the selected data unit, but you may, by using a simple keystroke, toggle between metric and data unit if required.
Data recording will still be metric to guarantee data integrity, but data outputs can be selected freely.

Surface positioning and motion (GPS, Gyro, IMU)

Setting up an entire vessel based project in NaviPac is easy performed using intuitive graphical definition tools. The video covers basic project definition, geodetics and vessel navigation setup.

Subsurface positioning (USBL, DVL, INS, Gyro, IMU)

Setting up remote and subsea vehicles is done in a similar manner to the main vessel – easy and intuitive. Adding instruments, positioning sources (transponders, INS, LBL etx) and defining weighting and Kalman filter settings is possible.

SBE - single beam echo sounder

Single beam echo sounders and other single source data suppliers can easily be interfaced in NaviPac, either via standard drivers or enhanced user-configurable drivers. Data will be available for display in both Helmsman’s Display and DataMon. Single source data can be shown as points clouds in the HMD – and you can automatically derive DTMs out of it.

FLS - forward looking sonar (wedge and mosaic)

NaviScan supports a series of forward looking sonars such as eg. Tritech, Didson and Norbit. The data will be interfaced and recorded in NaviScan and made available for display in HMD as both stand-alone wedge display and 3D wedge display in the Map views.

MBE multi-beam echo sounder (soundings and DTM)

Multi-beam echo sounder, laser and sidescan will be interfaced and recorded in NaviScan. Display and quality control is easily done in HMD by using raw point clouds, terrain models or data profiles. Using multiple windows allows for QC by looking at data density, model standard deviation etc. Built in semi-automatic cleaning tool enables instant delivery or preliminary DTM.

SSS sidescan sonar

Sidescan data is interfaced in NaviScan and recorded in the SBD data format. The data can be shown both in real-time and in replay in special waterfall data display. This data display will also enable target markings (eventing) and image management.

Subsurface positioning (USBL, DVL, INS, Gyro, IMU)

NaviEdit Header Editor allows the user to check an ROV setup.

NaviEdit Data Editor allows the user to view and QC sensor data via a series of graphical displays.

MBE multibeam echosounder (NaviEdit to NaviModel)

Data that is stored in NaviEdit can be imported into NaviModel.

Tide corrections

Predicted or observed tides can be imported into NaviEdit using user-defined import templates.

SVP corrections

CTD or SVP can be imported into NaviEdit using user-defined import templates.

SBP sub-bottom profiler

You are able to work with several SEG-Y files in NaviModel at the same time. When NaviModel is 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.

Change offsets, C-O's and mounting angles

Sometimes incorrect measured offsets, C-O’s or mounting angles are entered into the online acquisition system. NaviEdit Header Editor allows us to correct these errors.

Raybending corrections

Sometimes Sound Velocity values are incorrect and we need a tool to perform a local correction. In NaviEdit Data Editor we can visualise the Sound Velocity corrections before we apply them.

Sensor editing (import and manual editing)

These tools can be used to reject or accept DTM points.

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

Point Editor

Point Editor can be used to manually reject or accept DTM points using an eraser (square select) or a region (polygon select). This tool will soon be replaced with a newer version within NaviModel.

Import XYZ files

XYZ files 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 automated 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 files can be imported as DTMs or as point clouds.  

Point clouds can be displayed as one solid colour, as RGB values or as Intensity values.

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.

Large Point Clouds

Large Point Cloud Viewer supports Point Clouds of virtually unlimited size.

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.

Level out

Level out tool can be used to correct for small depth differences between surveys.

Smooth surface

Smooth surface tool smooths a DTM surface by an absolute distance or by the number of DTM cells.

CUBE

Combined Uncertainty and Bathymetric Estimator (CUBE) tool is available in NaviModel and is implemented alongside our other cleaning approaches.

Find Rocks

This tool analyses DTMs to identify rock events.

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.

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.
