van der Grinten II
Geocart menu class: Miscellaneous
Geocart family: van der Grinten
Neither conformal nor equal area
Meridians: Central meridian is straight. Other meridians are circular, equally spaced along the Equator and concave toward the central meridian.
Parallels: Equator is straight. Other parallels are circular arcs, concave toward the nearest pole.
Symmetry: About the central meridian or the Equator
True on the Equator. Increases rapidly with distance from the Equator.
Great distortion of area near the poles
The world is enclosed in a circle. All meridians intersect parallels at right angles, but projection is not conformal. Spacing of parallels along the central meridian is the same as that for Van der Grinten I.
World maps, but rarely
Presented by Alphons J. van der Grinten (1852–?) of Chicago in 1904
Lagrange is conformal.
Van der Grinten I has parallels that do not intersect meridians at right angles.
