Target class: coordinate reference frame Context triple: [Earth-centered Earth-fixed, instanceOf, coordinate reference frame]
-
A.
global reference frame
chosen
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.
-
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.
coordinate transformation
A coordinate transformation is a mathematical operation that converts the representation of points or vectors from one coordinate system to another while preserving their underlying geometric relationships.
-
D.
GNSS reference network
A GNSS reference network is a coordinated system of continuously operating GNSS stations that provide precise, stable positioning and timing references for surveying, navigation, and geospatial applications.
-
E.
reference meridian
A reference meridian is a designated line of longitude used as a starting point for measuring geographic coordinates and establishing time zones.
- 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.
