Winkel Tripel - GIS Wiki | The GIS Encyclopedia Winkel tripel projection - Wikipedia What are the pros and cons of using the Mercator projection? I have not used. What is the advantage of a Winkel Tripel map? - KOOLOADER.COM Follow All Geography Now on WordPress.com. Winkel coined the name "tripel" (meaning "triple" in English) to reflect the three step process: project into Cylindrical Equidistant, project into Aitoff and then average the two projections. 15 graticule. A compromise projection used for world maps that averages the coordinates from the equirectangular (equidistant cylindrical) and Aitoff projections. The Mercator projection map is the most popular but it is also riddled with inaccuracies. The diagram at the right side of the map shows how rapidly the map scale increases at higher latitudes. In Mercator the the latitide and longtitude lines stay straight.

Ancient Greek maps from the sixth century B.C. A common example is a cheating spouse who suspects their partner is being unfaithful. Winkel Tripel is supported on spheres only. Files are available under licenses specified on their description page. To make Rahul Narain's answer in comment a full answer: "WinkelTripel" can also be used in projection functions like GeoGridPosition: In Mathematica 10, functions like GeoGraphics will be able to use projections like this even more easily. Advantages: [] the Winkel tripel fares well against several other projections analyzed against their measures of distortion producing small distance errors small combinations of Tissot indicatrix ellipticity and area errors and the smallest skewness of any of the projections. Winkel TripelHelp | Documentation - Esri Differences: The Mercator projection is a more accurate projection than Winkel Tripel however the poles cannot be represented in Mercator. The Winkel tripel projection is widely used for world maps. What Is The Winkel Tripel Projection Good For? - Mastery Wiki It can also be defined as the transformation of spherical network of parallels and meridians on a plane surface.
