Target entity: Transverse Mercator Context triple: [Irish Transverse Mercator, projectionType, Transverse Mercator]
-
A.
Transverse Mercator
chosen
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.
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.
-
C.
Irish Transverse Mercator
Irish Transverse Mercator is a modern, high-precision map projection and coordinate reference system used for surveying and mapping across Ireland.
-
D.
Mercator projection
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.
-
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.
