Map projections are based on developable surfaces, and the three traditional families consist of cylinders, cones, and planes. They are used to classify the majority of projections, including some that are not analytically (geometrically) constructed.

This is a summary of map projections that have articles of their own on Wikipedia or that are otherwise notable. Because there is no limit to the number of possible map projections, [1] there can be no comprehensive list.

In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. [1] [2] [3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane.

2023年3月23日 · Three of these common types of map projections are cylindrical, conic, and azimuthal. Map projections inevitably introduce distortions in one or more of the following aspects: Area-preserving projection – Also called equal area or equivalent projection, these projections maintain the relative size of different regions on the map.

2023年3月1日 · Created using D3, Map Projection Transitions provides an excellent way to visualize a wide range of map projections. What is a Map Projection? How is the 3D surface of the earth modeled onto a 2D surface?

Map projections are mathematical transformations between geographic coordinates and plane coordinates. Many types of map projections have been devised to suit particular purposes. The term "projection" implies that the ball-shaped net of parallels and meridians is transformed by casting its shadow upon some flat, or flattenable, surface.

Because we’ve pumped out a goldmine of the top 50 global map projections used by cartographers today. From Aitoff to Winkel, these map projections are your blueprint for designing cartographic masterpieces.

As you’ve already learned, map projections are fundamental tools in cartography that aim to depict the Earth’s three-dimensional surface on a two-dimensional map. To achieve this, mapmakers utilize various mathematical techniques to transform the Earth’s curved surface onto different geometric shapes known as developable surfaces .

A map projection is the manner in which the three dimensional spherical surface of the Earth is represented on a two-dimensional surface of a piece of paper. The term ‘projection’ comes from the idea of placing a light source within a transparent globe and projecting shadows of the meridians, and parallels onto a sheet of paper placed ...

2017年4月25日 · Map projections are a systematic transformation of longitudes and latitudes of a location on the surface of the sphere. Map projections are important in creating maps with map projections distorting the surface in some way.
