Quality rating is an automated process and may not reflect the actual performance of the location. The best way to determine quality is to try it out yourself.
That being said, when you’re scanning, please be sure you’re following our Scanning Best Practices, such as moving slowly and smoothly, making sure there are no people in your scans, and taking scans throughout various times of day to get different lighting conditions (but please avoid scanning at night or when there isn’t sufficient light). Adding more high-quality scans may improve the quality rating of the location.
