6.10 Derived parcels

A derived parcel shall be reproducible from its source objects and derivation rule.

The record shall identify:

UID and parcel class;

source object UIDs and versions;

derivation date and process;

spatial operation or decision rule;

resulting geometry and CRS;

attributes inherited or calculated;

exceptions or manual adjustments;

quality checks performed; and

outputs in which the derived parcel is used.

When a source object changes, affected derived parcels shall be identified and reassessed before further controlled use.
