Accuracy Classes and Intended Use
Reality capture makes it easy to produce a number. It does not automatically make that number defensible. What makes a measurement usable downstream is the pair of statements attached to it: how it was derived, and what decision it was produced to support.
An accuracy band communicates the realistic tolerance achieved under the actual capture conditions — control, geometry, weather, surface. It is stated after processing, not promised in a proposal.
An intended-use statement is narrower than people expect. A measured roof area produced to support a repair bid is not automatically appropriate for a certified area determination. Saying so on the deliverable protects everyone.
When both statements are present, a qualified professional can decide whether the evidence fits their scope of work. When they are absent, the professional has to re-derive the data anyway.
