-
A.
Transverse Mercator
Transverse Mercator is a widely used map projection that represents the Earth’s surface on a cylinder aligned along a meridian, providing accurate large-scale mapping in narrow north–south zones.
-
B.
Mercator projection
chosen
The Mercator projection is a cylindrical map projection widely used for navigation because it preserves angles and directions but greatly distorts the size of landmasses near the poles.
-
C.
WGS84
WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
-
D.
Lambert conformal conic projection
The Lambert conformal conic projection is a map projection that preserves local shapes and angles, commonly used for aeronautical charts and regional maps in mid-latitude areas.
-
E.
UTM coordinate system
The UTM coordinate system is a global map projection and grid-based referencing system that divides the Earth into numbered zones to provide precise, metric-based location coordinates.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
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.
