Unverified50% confidenceFactExact time
In professional GIS workflows, each layer usually carries metadata, including data source, collection time, accuracy level and coordinate system, and common practices for confidence annotation include distinguishing by line type (solid line for confirmed, dashed line for inferred), distinguishing by transparency, or attaching attribute fields to record uncertainty ranges.
