NaviSuite Nardoa now supports EdgeTech eBOSS data

23 October 2025

EIVA is pleased to announce the first release of EdgeTech’s eBOSS sub-bottom imaging system data integration into NaviSuite Nardoa – our core software bundle tailored to pipeline and cable inspections. This new capability is specifically available in NaviModel version 4.11, extending the bundle’s modelling and visualisation strengths to include 3D sub-bottom data.

Survey teams can now process eBOSS data recorded in JSF format directly within NaviModel, with no need for specialised acquisition software or additional licensing. As with other supported sonar data types, eBOSS integration is included as standard in NaviSuite Nardoa.

Users can explore sub-bottom data in multiple views, mark targets, and determine burial depth – all within a unified, sensor-agnostic workflow designed to streamline post-acquisition processing and visualisation.

The diagonal profile view reveals the digitised cable path, maintaining a consistent depth through the dataset. The upper edge of the profile marks the limit of sonar coverage — not the seabed.

Georeferenced and time-stamped: enabling seamless integration of sub-bottom data with broader survey datasets

With eBOSS data now supported, users can load and navigate through sub-bottom data in both 2D and 3D views, mark targets such as cables or UXOs, and estimate burial depth – all within the familiar NaviModel environment.

The data is georeferenced and time-stamped, allowing it to be combined with other survey data types for a comprehensive overview.

Note: The data processing solution is based on standard JSF recording from EdgeTech.

Introducing the Sub-bottom Imaging Frame

The Sub-bottom Imaging Frame is a new addition to EIVA’s portfolio (currently under development), designed to enhance sub-bottom profiling capabilities by integrating third-party technologies. This integration is particularly relevant for survey operators using ScanFish platforms, where EdgeTech’s eBOSS system is already deployed – but it also supports a wide range of survey configurations where sub-bottom profiling is required.

First showcased at EIVA Demo Days Denmark in September 2025, the frame drew strong interest from clients. By enabling support for eBOSS data, EIVA reinforces its commitment to interoperability and operational efficiency.

This frame development complements the latest update to NaviSuite Nardoa. Together, the integration offers a more complete solution for sub-bottom investigations.

Key benefits of the NaviSuite Nardoa update include:

Standardised interface for EdgeTech JSF format – no need for specialised acquisition software
Multi-view data visualisation (top view, cone display, along-track)
Target digitisation in 2D/3D and intensity control for enhanced detection
Interactive navigation and bottom tracking
Integration with existing NaviModel workflows

Whether you're conducting cable route inspections, UXO surveys or other seabed investigations, this new feature helps streamline your operations and reduce post-processing time.
