Ellipsoid free world vector map.The Robinson map projection is shown centered on Greenwich.
The meridians are regularly distributed curves mimicking elliptical arcs. They are concave toward the central meridian and do not intersect the parallels at right angles. The parallels are unequally distributed straight lines. The equator, both poles, and the central meridian are projected as straight lines.
The Robinson projection is a commonly used world map cylindrical projection. The Robinson projection was created in 1963 by Arthur H. Robinson upon a request by Rand McNally, a commercial atlas publishing company.
