Core checks for this topic
- Confirm the source coordinate reference system, datum realization and units before processing.
- Validate geometry, control points and attribute fields on a small sample first.
- Compare the processed sample with independently known coordinates or measurements.
- Record the method, parameters and tolerances used so the deliverable can be audited.
