How to Use EIVA NaviEdit 9.1.0

Getting started with EIVA NaviEdit 9.1.0 is designed to be as efficient as possible, though mastering its full capability requires practice.

Step 1: Starting a New Project
Open the software and create a new project. Set the directory and project name. The project will organize all your files, configurations, and processed data in one place.

Step 2: Importing or Connecting Data
You can either import data from a supported file (e.g., .xtf, .all, .gsf) or, if you have a compatible system, connect directly to a live data stream for real-time data editing. You can add multiple files to a single project to work on a larger survey area.

Step 3: Navigating the 3D View
Use the mouse (pan, rotate, zoom) to navigate the 3D seabed model. The software uses a multi-view setup, allowing you to see the data from plan, profile, and 3D perspectives simultaneously. This makes identifying anomalies much easier.

Step 4: Identifying and Editing Anomalies
Use the editing tools to clean your dataset. The CUBE algorithm can be run to automatically flag and clean data points that do not fit the statistical model. For manual editing:

• Use the Swipe Editor to selectively accept or reject soundings by painting over them.

• Use polygon selections to remove groups of unwanted points (e.g., noise from ship’s propeller wash).

• Use profile editing to view a single cross-section of the seabed and adjust for tide or navigation errors.

Step 5: Validating and Saving
Once editing is complete, run a validation check to ensure no data integrity issues remain. Finally, export your cleaned, validated data in a format ready for final processing, chart creation, or delivery to the client.
