# NavVis VLX Quality Map Checklist

Before finishing a scan, check the quality map using the following checklist:

### General scan quality checks

- [ ] **Trajectory continuity:** Check the path is continuous; no visual breaks or sudden jumps in the quality map.
- [ ] **Overlap trajectories:**Check that across rooms/hallways there is sufficient trajectory overlap.
- [ ] **Loop closures:** Completed loops visibly connect; start/end paths meet cleanly.
- [ ] **Control points (if used):**Placed and captured.
- [ ] **Coverage**: All intended areas visited; no blind spots.

### **Panorama quality checks**

- [ ] **Panorama icons are visible**: Confirm (360° ![](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/quality-map-checklist-image-usnwzn45.png) display on the quality mapthroughout the scanned area.
- [ ] **Sharpness**: From the scanning screen, open each panorama and rotate or zoom to check for moving people or objects. Confirm there is no motion blur.
- [ ] **Even panorama distribution**: Check that panoramas aren't clustered in one area with large gaps elsewhere; coverage should be reasonably consistent across the whole dataset.
- [ ] **Coverage**: Confirm major junctions, thresholds, and key assets are represented on the map. Add supplemental panoramas where documentation value is high.
- [ ] **360° panoramas placed where needed**: If full 360**°** coverage was required (e.g. for specific deliverables), confirm 360° panoramic icons are present at those locations.
- [ ] **No panorama-free dead ends**: Check that corridors or rooms that were scanned to the end and turned around still have a panorama captured before exiting.
- [ ] **Consistency**: Panorama spacing roughly follows the plan; density increases only where complexity warrants it.
- [ ] **Point cloud will be colored**: Since panoramas drive point cloud colorization, any area with no panorama icons will have an uncolored point cloud. ![A map showing pathways and highlighted points for navigation or analysis purposes.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/pano_distribution.png)
