What do you call a flattened globe

The Mercator projection is being applied in varying patterns, such as by taking a cylinder to touch a globe with the axis of cylinder intersecting that of the globe at the right angle, leaving the cylinder to touch any single meridian.

By that way, a central Meridian is created. When the cylinder is unrolled, the area adjacent to the central meridian will have constant scales. This type of projection is commonly used to display different parts of the Earth.

It maintains area around the central meridian. The equator is a straight horizontal line intersecting the central meridian at a right angle. Other meridians are curved lines, while other parallels are straight lines. This map projection was initiated by Karl B. Mollweide in However, there is more scale accuracy in the equatorial regions. The projection is ideal for making global maps.

All the parallels are straight lines perpendicular to a central meridian, while other lines are curved like those in the Mollweide projection.

The values of sine curves are used to create meridians, making the meridian spacing wider than that of the Mollweide projection. The Sinusoidal projection is typically used for map making of the equatorial regions such as in South America and Africa. This type of equal-area projection is a combination of the Homolographic and the Sinusoidal. Normally, the Sinusoidal projection is applied between the 40 degrees south and 40 degrees north latitudes, grafted to the Homolographic in the areas out of the above mentioned range.

As the two projections can not match perfectly, small kinks are seen on the meridians where the two projections match. Skip to main content. You are here Home. Planar, Azimuthal or Zenithal projection This type of map projection allows a flat sheet to touch with the globe, with the light being cast from certain positions, including the centre of the Earth, opposite to the tangent area, and from infinite distance. This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection.

Gnomonic projection The Gnomonic projection has its origin of light at the center of the globe. Stereographic projection The Stereographic projection has its origin of light on the globe surface opposite to the tangent point. Conic projection This type of projection uses a conic surface to touch the globe when light is cast. When the cone is unrolled, the meridians will be in semicircle like the ribs of a fan.

The tangent areas of conic projection can be classified as central conical projection or tangent cone, secant conical projection, and polyconic projection. Central conical projection This simple map projection seats a cone over the globe then casts the light with the axis of the cone overlapping that of a globe at tangent points. Secant conical projection The projection uses a conical surface to intersect the surface of a globe, creating two tangent points and subsequently two parallels.

These circles are all the same size on the globe. The Mercator distorts size to preserve shape. For a more accurate view of land area look at the Gall-Peters projection, which preserves area while distorting shape. Wikimedia Commons. In the end, there's not "right" map projection. Each comes with trade-offs, and cartographers make projection decisions based on the particular tasks at hand. But if you are interested in seeing an accurate depiction of the planet, it's best to stick with a globe.

All maps are wrong. Gall-Peters This is a cylindrical world map projection, that regains accuracy in surface area. Image - Daniel R Strebe 5. Sinu-Mollweide Developed in by Allen K Philbrick, this projection fuses the Sinusoidal projection , which was first used in the 16th Century, with Karl Brandan Mollweide's map of and challenges our assumption of how the flattened globe should look. Still an equal area projection that maintains fidelity of area, we like this projection for its bold graphic view.

We printed this little known projection to celebrate our fifth anniversary and it is now a popular part of our main collection. You can buy one here now. Image - Daniel R Strebe 7. Image - AuthoGraph 8. Hobo-Dyer Developed in , this map is know as cylindrical projection because of its straight lines of longitude and latitude. Shape is sacrificed in order to represent countries in their correct proportional size. This is done by narrowing the lines of latitude as they approach the poles, in order to compensate for the missing convergence of the lines of longitude.

Peirce Quincincial Whilst not used greatly for geographic purposes we like this alternative conformal map projection developed by Charles Sanders Peirce in The projection is presented with the North pole at the centre and four quadrants around this giving you a projection that can be tiled perfectly.
