This paper discusses the concept of metrological traceability to the International System of Units (SI) unit of length, the meter. We describe how metrological traceability is realized, give a recent example of the standardization of laser trackers, and discuss progress and challenges to the traceability of 3D imaging data. i steven.phillips@nist.gov ii US customary units based on inches are defined in terms of, and realized by, the meter; 1 inch = 0.0254 meter exactly. iii In 1875 the "treaty
