Which practice helps minimize map distortion when presenting geographic data?

• A. Only use the most aesthetic projection regardless of distortion.
• B. Projection choice does not affect map distortion.
• C. Careful projection to minimize distortion in area, shape, distance, and direction.
• D. Distortion is unavoidable; projection choice is irrelevant.

Answer: (C)

Maps flatten a curved Earth, so some distortion in area, shape, distance, or direction is unavoidable. The main idea is to choose a projection with the properties you need for the map’s purpose, minimizing the distortions that matter most for that use. This is why careful projection to minimize distortion in area, shape, distance, and direction is the best approach: by selecting a projection that preserves the aspect you care about—equal-area for comparing sizes, conformal for preserving shapes, equidistant for measuring distances along lines, or true-direction for accurate bearings—you reduce the misleading effects of distortion. No single projection can keep all four properties perfect, so the goal is to match the projection to the map’s purpose and the geographic extent being shown. Aesthetics alone won’t solve distortion, since even a visually appealing projection introduces trade-offs.
