azimuthal equidistant projection
A map projection where distances from the center point are true to scale and directions from the center are correct. Used in cartography and geography.
In an azimuthal equidistant projection, distances and directions from the center are accurately represented.
The United Nations flag uses a world map drawn with the azimuthal equidistant projection.
Mercator projection preserves angles and shapes locally but distorts area, especially near the poles, unlike the azimuthal equidistant projection which preserves distances and directions from a central point.
Equidistant conic projection preserves distances along meridians and standard parallels, while azimuthal equidistant preserves distances from a single central point.
Compound of 正距 (true distance), 方位 (direction), and 図法 (projection method). The term directly describes the projection's properties.
