-
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.
National Spatial Reference System
The National Spatial Reference System is the official coordinate framework used in the United States to define precise locations, elevations, and boundaries for mapping, surveying, and navigation.
-
D.
WGS84
WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
-
E.
Lambert-93
Lambert-93 is a French national projected coordinate reference system based on the Lambert conformal conic projection, widely used for mapping and geospatial data across mainland France.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
