Maps, data and evidence
Understand evidence grades
Know the difference between discovered, owner-reported and independently confirmed facts.
Read the evidence ladder
- Public discovered: a dated source reports the value or feature.
- Owner reported: the asset owner states it, with or without a supporting document.
- Document evidenced: an uploaded document and page support the fact.
- Counterparty reported: a carrier, buyer, supplier or operator replies through the evidence workflow.
- Verified: the relevant authority or professional confirmation is recorded.
Resolve contradictions
PV8 keeps competing observations visible until an authorised person accepts one as the current fact. The rejected value remains in the audit trail rather than disappearing.
