EIVA NaviEdit 9.1.0: Specialized Software for Bathymetric Data Post-Processing

EIVA NaviEdit 9.1.0 is a dedicated post-processing software application designed for the detailed editing, cleaning, and finalization of bathymetric data collected during marine surveys. It is the critical next-step software used after data acquisition with EIVA NaviPac, transforming raw soundings into a clean, validated, and deliverable dataset.

Core Philosophy: Precision Data Cleaning for Definitive Results

While NaviPac handles real-time acquisition, NaviEdit focuses on the meticulous, offline refinement of that data. Its purpose is to remove noise, artifacts, and errors to produce the most accurate digital terrain model (DTM) of the seabed possible.

Key Features & Capabilities in NaviEdit 9.1.0

1. Advanced Data Cleaning & Filtering

• Interactive Sounding Editor: The core tool. Users can manually review and edit individual soundings or groups of soundings in profile, plan, and 3D views to remove spikes, dropouts, and other anomalies.

• Automated Filters: Apply systematic filters based on statistical parameters (e.g., depth difference, across-track distance) to perform bulk cleaning while maintaining manual oversight.

• Water Column Editing: Specifically target and remove residual water column noise from multibeam echosounder data that was not eliminated during acquisition.

2. Comprehensive Data Review & Analysis

• Multi-View Visualization: Synchronized display of data in multiple views (2D plan, swath profile, 3D perspective) allows for confident identification of erroneous soundings.

• Data Comparison Tools: Overlay data from different survey lines or passes to identify inconsistencies and ensure seamless data merging.

• Quality Control (QC) Metrics: Visualize and analyze data density, coverage, and uncertainty indicators to ensure the final product meets project specifications.

3. Surface Generation & Modeling

• Triangulated Irregular Network (TIN) Creation: Generate high-quality, non-gridded surfaces from the cleaned point cloud, which better represent complex seabed features like rocks or pipelines.

• Gridding Algorithms: Create regular grids (DTMs) from the cleaned data for export to charting or GIS systems.

• Contour Generation: Derive smooth, accurate depth contours from the final surface model.

4. Workflow Integration & Reporting

• Seamless NaviPac Integration: Directly import raw data logged by NaviPac, preserving all sensor, navigation, and tide corrections applied during acquisition.

• EIVA Ecosystem Workflow: Cleaned data and surfaces are easily passed to EIVA NaviModel for further analysis, charting, and report generation.

• Audit Trail & Reporting: Maintains a complete edit history and allows generation of data processing reports for client deliverables.form
