Better data out than came in
What happens to your register in the field.
Confirmed
Inspected and recorded against your own asset reference.
Corrected
Positions and attributes fixed on site. The original value, who changed it and when are kept.
Found in the field
Assets missing from the register captured on site and flagged as additional.
Not present
Assets that no longer exist are marked — kept in the record, out of the outstanding work.
Grouped
Individual trees brought together into a belt when that's how they're managed.
Evidenced
Photographs attached to the specific inspection, surveyor and date.
Provenance
Every value has a history.
When a surveyor moves an asset or corrects an attribute, Arbrium records the field, the value you supplied, the new value, who made the change and when. Imported attributes are kept exactly as supplied alongside the working record, and your own references stay attached from import to export.

Decisions on the record
Who confirmed it, and when.
Relationships carry their own provenance: whether a rule or a person suggested them, the evidence — such as the distance between the assets — and the asset owner's decision.
Decisions are stamped by the system with who made them and when, can't be rewritten, and keep their history if they're later reopened.
