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.

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.

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.

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?

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 .

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.

2017年11月21日 · Map projections are necessary for mapping the surface of the earth onto a flat surface because it’s impossible to portray spherical objects on a flat surface. Map projections are used across all fields, from geographical maps, to globes, satellite images, relief maps and …

2024年12月17日 · Mapmakers and mathematicians have invented dozens of map projections — the possibilities are almost limitless. As new needs arise — such as the need to project satellite imagery onto a computer screen with minimal distortion — new projections are invented. Most older and common projections are one of these three developable surfaces.

2025年2月4日 · Map projections display the earth's surface (a round object) on a flat object like paper or on a screen. When a map is unprojected, GIS systems use the Geographic Coordinate System(GCS) to perform functions. GCS uses latitude and longitude and uses degrees as its unit to accurately depict locations on a sphere. When a map is projected, GIS ...
