Is ZF + Def a conservative extension of ZFC+HOD? the National Geographic Society made the Winkel Tripel as its map projection of The Winkel Tripel projection, chosen by the National Geographic for its world maps, represents the poles more accurately than the Mercator, but it still distorts Antarctica badly and creates the illusion that Japan is hugely to the east of California, instead of its nearest neighbor to the west. This page was last modified on 2 June 2010, at 20:02. Winkel Tripel Projection - Manifold Naturally, this projection is neither conformal, nor equal-area. Since the meridian is a true north-south line, the angle will give the compass bearing to be followed. Equidistant Cylindrical and Aitoff (not Hammer-Aitoff) projections. What are some advantages of the gall Peters Projection? The reticle is 15 degrees in latitude and longitude. For example, lines of latitude in a Robinson projection are parallel straight lines, while in a Winkel Tripel they are slightly curved, nonparallel lines. When would you use a Winkel Tripel projection? As the map reaches closer to the poles, the spacing increases so much that the map must be cut off at some arbitrary parallel, such as 80 N. This change of scale enlarges features near the pole.
