Major Projection Families

Projections group by geometric surface used:

• Cylindrical (e.g., Mercator): Good for equatorial regions, distorts poles severely
• Conic (e.g., Albers): Best for mid-latitudes, used for most national maps
• Azimuthal (e.g., polar): Shows true direction from center point, used for polar and air navigation maps

The Robinson projection deserves special mention as a deliberate compromise. It does not perfectly preserve area, shape, distance, or direction. Instead, it minimizes all distortions simultaneously, making it the most visually balanced world map.
