-
B.
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.
-
C.
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.
-
D.
plateau
A plateau is a broad, elevated, and relatively flat landform that rises sharply above the surrounding area.
-
E.

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.
