2D/3D Scan Visualization
Upload a DroneRover CSV scan file to PolarWave Data to generate advanced 2D and 3D visualizations with signal processing filters — without needing third-party software like Surfer.
Step 1 — Log In
Go to www.polarwave.app and sign in with your credentials.
Step 2 — Navigate to Scans
From the dashboard, open the Magnetometer tab in the left-hand menu and select Scans.
Step 3 — Upload Your Scan File
- Click Select File (or drag and drop your file into the upload area).
- Choose your DroneRover CSV export file (e.g.,
dronerover_data_20250304_142750.csv). - From the Supported Device dropdown, select: TreasureHunter3D → DroneRover
- Click Upload.
The upload expects the standard DroneRover CSV export. Export it from the DroneRover app using Share → Share CSV. See Exporting & Sharing Scan Data for instructions.
Step 4 — Open the 3D Viewer
Once the upload completes, your scan appears in the scan list. Click View to open the interactive 3D viewer.
Step 5 — Configure Visualization Settings
The default view may look flat or noisy. Apply these two settings first:
1. Enable Decimation
In the settings panel on the left, expand Decimation and check Enabled.
| Setting | Recommended value |
|---|---|
| Function | Maximum |
| Step | 10 |
Decimation reduces noise by keeping only peak values within each step window, which makes buried objects stand out more clearly.
2. Enable Averaging
Expand Averaging and check Enabled.
| Setting | Recommended value |
|---|---|
| Size | 3 |
Averaging smooths the signal across neighbouring data points, reducing random spikes and making genuine anomalies easier to identify.
Optional: Fine-Tune the Display
| Setting | Description |
|---|---|
| Soil Type | Adjusts signal scaling for your terrain type — try different options to improve contrast |
| Invert Signal | Flips the data so positive anomalies appear as peaks rather than valleys (or vice versa) — useful when targets show as dips |
After applying Decimation and Averaging, zoom and rotate the 3D view to inspect peaks from multiple angles. Red/warm-coloured peaks are the strongest anomalies and the best candidates for ground investigation.
