01The operating question
Environmental materials may come from different dates, equipment, or external parties. Without collection conditions, versions, and intended use, similar images or values cannot be compared directly or treated as professional conclusions.
02Working method
Start with one material type or observation task, recording its source, authority, time range, and quality notes. Then define batch management, exception comments, human review, and results handover. Professional sampling, testing, and assessment remain with appropriately qualified organisations.
