Which projection does not produce a conformal map?

• A. Lambert Conformal Conic
• B. Winkel Tripel
• C. Mercator Projection
• D. Stereographic

Answer: (B)

Conformality means preserving local angles and shapes at every point on the map. The Winkel Tripel projection is a compromise that aims to minimize overall distortion by averaging two different projections, so it does not preserve angles everywhere. Small shapes can be slightly stretched or squashed depending on location, which is why it is not conformal. The other three projections preserve angles locally: Mercator keeps a consistent scale in all directions so angles are preserved, stereographic projection maps circles to circles and preserves angles, and Lambert Conformal Conic is specifically designed to be conformal. So the Winkel Tripel is the one that does not produce a conformal map.
