Survey data editing

NaviEdit allows for editing of overall survey settings, raw sensor data and geodetic settings. This applies to data recorded with NaviSuite products as well as third-party software products, such as Kongsberg SIS, Hypack, GSF, etc.

The software comes in two variants:

  • NaviEdit Lite, which is restricted to import of single source input data types
  • NaviEdit Pro, the variant described here, which offers the most extensive list of features.

NaviEdit Pro enables import of various types of laser and sonar data, including multi-beam echo sounders and side-scan sonars. Moreover, it can be used for seismic streamer positioning.

Please note that the software requires a Microsoft SQL database. The free version, SQL Server Express, is included in the software. For NaviEdit to use a data base larger than 10 GB would require a SQL Server Standard (or Enterprise) version.

Let software do the hard data processing work

Among other features, NaviEdit Pro includes the Workflow Manager – Desktop tool, which you can learn more about below.

    Get the most out of your survey data...

    ... by having NaviEdit fix all the errors and problems in the data

    NaviEdit ensures that you get the most out of your survey data by fixing all the errors and problems in the data – regardless if these have arisen during the survey because of sensor errors, human errors or environmental impact.  

    Examples of what NaviEdit can be used for

    • Changing mounting angles/offsets/C-O
    • Switching between sensors, in case of (periodic) sensor dropout
    • Smoothing or de-spiking of faulty/noisy sensors
    • Correction for tide, including GPS tide calculations
    • Sound velocity profile corrections – applying nearest SVP measurement or even synthesising an SVP if you do not have one
    • Removing swell
    • Calculation of pressure to depth, including utilising CTD profile and UNESCO formula
    • USBL recalculation and weighting
    • Changing geodetics
    • Recalculating final result from GPS antenna to seabed

    Moreover, NaviEdit keeps all raw data with angle/distance values. Consequently, you always have access to these and thus the possibility of editing them, fixing any problems seen further along in the editing workflow

    It also means that changes often are instantaneous. For example, changing a mounting angle does not require data to be recalculated. When importing data to software for data visualisation such as NaviModel, this will connect directly to NaviEdit. If NaviModel is used, changes made in NaviEdit are reflected in the data being displayed and processed in the visualisation software.

    Workflow Manager – Desktop

    The NaviSuite Workflow Manager software tool is designed to enable a previously unseen degree of automatic data processing.

    Workflow Manager – Desktop

    Let software do the hard data processing work

    The Workflow Manager is a configurable workflow process automation tool. In other words, it allows you to automate the small steps you normally go through when processing subsea data.

    The software is designed to enable a previously unseen degree of automatic data processing of massive amounts of subsea sensor data.

    The Workflow Manager is a configurable workflow process automation tool

    The Workflow Manager is a configurable workflow process automation tool

    The Workflow Manager software comes in two variants:

    Workflow Manager – Desktop will be available for free when purchasing NaviEdit Pro and NaviModel Producer licences (the NaviSuite products dedicated to navigation/positioning and data modelling/visualisation respectively) during the beginning of 2019. It is currently in operation with and being tested by selected customers before official release. If you would like to learn more about the tool, please feel free to reach out to us.

    This variant is limited to being able to run one NaviEdit and one NaviModel task in parallel, whereas Workflow Manager – Server can run an unlimited number of NaviEdit and NaviModel workflow steps in parallel (typically 30-100), resulting in a significant parallelisation of processing for large data sets, and significant savings in terms of man-hours spent on data processing.

    Key benefits

    • Faster data processing throughout your project through fewer manual tasks
    • Better utilisation of your data processing staff’s time and competences

    The optimal choice for hydrographic surveys carried out with a single boat

    Workflow Manager – Desktop is especially relevant for use during shallow water surveys (in combination with NaviSuite Kuda software), where sonar and terrestrial LiDAR data is processed as you sail.

    The Workflow Manager will automatically process each sonar and laser file as it is recorded, thus completing most of the processing during acquisition, leaving quality control as the only task for the data processer to carry out onshore. For those customers streaming data to the shore, the Workflow Manager can run either onboard before streaming, or onshore receiving streamed data.

    Increasing amount of data processed in less time

    Workflow Manager – Desktop can be applied to functions in NaviEdit Pro and NaviModel Producer (special versions of NaviEdit and NaviModel that run without a user interface are made available together with the Workflow Manager). The tool is also able to activate third-party scripts and tools.

    The Workflow Manager tool will improve your data processing efficiency as:

    • Repetitive tasks are automated
    • Data processing staff can focus on errors, interpretations and quality control
    • Many features normally carried out in NaviEdit and NaviModel are not only automated but have also been performance optimised for use with the Workflow Manager

    The result is a powerful cocktail of high-speed data processing features.

    How it works

    You define the sequence of processing steps. With the setups we have seen so far, the task of defining your workflow is minimal – although it often gives you food for thought as to how you can optimise the way you work.

    There are many types of steps available. A few examples are:

    • Loading files, including waiting for files to become available
    • Applying tide, SVP, etc
    • Cleaning data in NaviModel
    • Checking a number of quality control parameters such as density, gaps, noise levels, TVU, etc
    • Correcting seabed height level across multiple surveys, etc
    • Exporting data in different formats

    When processing data, the Workflow Manager will visually show the operator which steps are being performed and their status by icons:

    • Current steps (blue): The currently running step(s) that are executed in parallel. You can define how many parallel tasks the Workflow Manager should use to ensure that it matches the capacity of your computer.
    • Completed (green): The step has been completed successfully.
    • Error (red): When an error is encountered, the processing of the specific step stops, and the operator can decide what to do by investigating the error in NaviEdit/NaviModel, manually change the data as necessary, and restart the automatic processing from a given step.
    • User action (yellow): The tool can be set up to stop at a given point when carrying out a specific task. This is useful for processing steps that require manual quality control or steps that require operator-provided data or interpretation before the task can continue.

    All processing steps are logged. This means that the Workflow Manager provides a fully detailed survey log for later use, showing what was done by an operator or the tool and with what result.

    Keeping an eye of processing performance optimisations

    The Workflow Manager has a built-in performance measurement tool that measures the time spent on each processing step, so it is very easy to see how much time each part of the workflow takes, and consequently where it is worth optimising.

    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.

    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.
