Target class: Earth ellipsoid model Context triple: [GRS80, instanceOf, Earth ellipsoid model]
-
A.
reference ellipsoid
chosen
A reference ellipsoid is a mathematically defined, smooth, oblate spheroid that approximates the shape of the Earth (or another celestial body) and serves as a standard surface for geodetic calculations and coordinate systems.
-
B.
terrestrial globe
A terrestrial globe is a three-dimensional, spherical model of Earth that accurately represents its continents, oceans, and geographic features at a reduced scale.
-
C.
topographical model
A topographical model is a conceptual representation that maps the spatial features and relationships of a terrain or surface, often including elevation, contours, and physical landmarks.
-
D.
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.
-
E.
Earth rotation parameter
An Earth rotation parameter is a quantitative measure that characterizes variations in the Earth's rotation, including changes in rotation rate and orientation of the rotation axis relative to a reference frame.
- 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.
