Which projection preserves directions from the map center to all points, typically showing one hemisphere at a time?

• A. Azimuthal Projection
• B. Mercator Projection
• C. Miller Projection
• D. Cassini Projection

Answer: (C)

Azimuthal projections preserve the direction from the map center to every point. In these maps, the bearing from the center to any location remains accurate, even though distances and shapes can be distorted as you move away from the center. Because of this, a view centered on a point often shows one hemisphere at a time, typically in a circular disk. Other projections aim to preserve different properties: the Mercator projection keeps local angles (conformality) for navigation, but it does not maintain exact center-to-point directions across the whole map; the Miller projection focuses on balancing area and shape rather than azimuths; Cassini has its own distortion priorities and likewise doesn’t guarantee center-to-point directions. So the projection that best preserves directions from the map center to all points and is commonly used to display one hemisphere at a time is an azimuthal projection.
