Which projection is described as an equirectangular projection with evenly spaced parallels and meridians?

• A. Gnomonic Projection
• B. Mercator Projection
• C. Stereographic Projection
• D. Cylindrical Projections

Answer: (D)

An equidistant cylindrical (equirectangular) projection is described here. It maps the globe onto a rectangle with both parallels and meridians drawn as straight, evenly spaced lines, creating a simple rectangular grid. That uniform spacing is the key feature of cylindrical projections, specifically the equirectangular form. The other projections differ in how they handle the grid: gnomonic uses a tangent plane and doesn’t keep grid spacing uniform; Mercator is cylindrical but stretches parallels as you move away from the equator, breaking even spacing; stereographic is an azimuthal projection, not a cylindrical one, so it doesn’t produce a rectangular grid.
