The USGS has also conceived and designed several new projections, including the Space Oblique Mercator, the first map projection designed to permit mapping of the Earth continuously from a satellite with low distortion. The mapping of extraterrestrial bodies has resulted in the use of standard projections in completely new settings.
A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections. Depending on configuration, the projection also may map the sphere to a single diamond or a pair of squares. Hybrid of Collignon + Lambert cylindrical equal-area.
A flat map can show one or more--but never all--of the following: True directions. True distances. True areas. True shapes. Different projections have different uses. Some projections are used for navigation, while other projections show better representations of the true relative sizes of continents. For example, the basic Mercator projection ...
Jan 15, 2024 · In the Selection Form you can choose two projections from the menus; in the List of projections you can see the names of and some basic information about the provided projections – again, you can choose two of them to compare. (at the time being, this might not work on small screens) ; in the Selection via Thumbnail you can pick the desired ...

Mercator projection.
Apr 25, 2017 · Pseudoconic Projections are projections with parallels which are circular arcs with common central points. Unlike conic projections, the meridian is not constrained to be a straight line. Examples of pseudoconic projections include "bonne", which is an equal-area map projection. The maps are not constrained to rectangles or discs.
How to Select the Right Projection . Keep in mind that all projections either disort or preserve one of the following properties: Area/Size. Size of a feature on the map is the same relative to its size on the earth. Shape/Angle. Shapes appear the same on a map as they do on the earth Maps that preserve shape are called conformal. Distance
