Measurement ledger

Perimeters kept separate

An operational area estimate and an EFFIS satellite-mapped burnt-area perimeter may cover different objects at different times. Auburn neither merges them nor silently chooses one.

A remote-sensing perimeter/area estimate kept separate from national or incident-command reported hectares.
