Frequently Asked Questions
Where does the data come from?
Our US dimension stone data is derived from the Mine Safety and Health Administration (MSHA) public records, enhanced with geocoding, material classification, and operator inference. We only display verified and high-confidence records.
How accurate is the data?
Each quarry has a confidence score based on our classification rules. We only display records with confidence scores of 80% or higher in public views.
What's included in the CSV export?
CSV exports include mine ID, site name, operator details, location (state, county, coordinates), material types, activity status, and confidence scores.
