Coordinate Systems
Geodetic Reference Frames data format
This note is part of the Geodetic Reference Frames topic in the Coordinate Systems section of the Knowledge Center.
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.
