In which projection does the equator appear as a horizontal line and the poles lie at their correct surface distance from the equator?

• A. Polyconic Projections
• B. Lambert Conformal Conic Projection
• C. Gnomonic Projections
• D. Mercator Projections

Answer: (A)

The main idea is how a projection handles latitude lines and the spacing between them, especially along the meridians. The polyconic projection is built so that the equator maps to a straight, horizontal line on the plane, and the spacing along meridians increases in step with true latitudinal distance from the equator. This means the poles land at their correct surface distance from the equator, preserving that measured distance along meridians up to the poles.

This combination—equator as a horizontal line and true pole-to-equator distance along meridians—is characteristic of the polyconic construction. Other projections do not offer both properties simultaneously: Mercator preserves angles but distorts distances toward the poles (the poles effectively move away in distance), Gnomonic behaves very differently with distance and visibility, and Lambert Conformal Conic focuses distortion control around standard parallels rather than preserving pole distances from the equator.
