-
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.
UTM coordinate system
chosen
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.
-
C.
WGS84
WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
-
D.
Irish Transverse Mercator
Irish Transverse Mercator is a modern, high-precision map projection and coordinate reference system used for surveying and mapping across Ireland.
-
E.
Universal Polar Stereographic system
The Universal Polar Stereographic system is a global map projection and coordinate reference system specifically designed for accurate mapping of the Earth's polar regions, complementing the UTM system at high latitudes.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
