Target class: geographic coordinate system Context triple: [Ordnance Survey National Grid, instanceOf, geographic coordinate system]
-
A.
geodetic coordinate system
A geodetic coordinate system is a reference framework that specifies locations on or near the Earth's surface using latitude, longitude, and often height relative to a defined ellipsoidal model of the Earth.
-
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.
projected coordinate system
chosen
A projected coordinate system is a spatial reference framework that represents locations on the curved surface of the Earth using a flat, two-dimensional map projection with defined units, origin, and projection parameters.
-
D.
geodetic standard
A geodetic standard is an agreed-upon reference framework, model, or set of conventions used to define positions, shapes, and measurements on or near the Earth’s surface consistently and accurately.
-
E.
geodetic reference point
A geodetic reference point is a precisely surveyed physical location on the Earth's surface used as a fixed coordinate reference for mapping, surveying, and geospatial measurements.
- 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.
