Target class: metrological reference Context triple: [CODATA recommended values of the fundamental physical constants, instanceOf, metrological reference]
-
A.
reference meridian
A reference meridian is a designated line of longitude used as a starting point for measuring geographic coordinates and establishing time zones.
-
B.
geodetic datum
A geodetic datum is a reference framework consisting of a defined origin, orientation, and scale used to precisely locate points on the Earth’s surface in terms of latitude, longitude, and elevation.
-
C.
scientific measurement scale
chosen
A scientific measurement scale is a standardized system or continuum used to assign numerical or categorical values to observed phenomena, enabling consistent quantification, comparison, and analysis in scientific research.
-
D.
global reference frame
A global reference frame is a fixed, overarching coordinate system used to consistently define positions, orientations, and motions of objects throughout an entire modeled world or environment.
-
E.
principal meridian
A principal meridian is a primary north–south reference line used in land surveying to establish a coordinate framework for mapping and property boundaries within a specific region.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
