Export Intensity CSV
Export intensity values as CSV.
Use this when
You want the raw sonar return values for every ping — one value per sample depth — as a spreadsheet. This is useful for signal analysis or building custom visualizations outside HumVision.
Before you start
Open a recording and confirm that sonar data has loaded on the active channel. The intensity CSV only reflects the currently active channel.
Export the file
- Open a recording in the viewer.
- Click Export in the toolbar.
- Click Export Intensity Data (CSV).
- Choose a save location and click Save.
What the file contains
Each row is one ping. Columns are:
| Column | Contents |
|---|---|
ping | Sequential ping index starting at 0 |
s0, s1, … sN | Raw sonar return value at each sample depth, from nearest to farthest |
The number of sample columns (N) matches the longest ping in the recording. Shorter pings leave trailing columns empty.
Values are integers from 0 to 255. Higher values indicate stronger returns.
What you should see
A save dialog opens. After you save, a confirmation appears: "Intensity data saved." The file is named intensity-data.csv by default.
If it does not work
- "There is no intensity data to export" toast — the active channel has no pings. Switch to a channel that shows sonar data and try again.
- File opens with one header row and no data — the recording is still loading. Wait for it to finish, then export again.
- Export button is greyed out — HumVision is in sample mode or your account is inactive. Activate HumVision to export from real recordings.
