圆柱投影

¥Cylindrical projections

圆柱投影将球体投影到包含它的圆柱体上，然后将圆柱体展开到平面上。伪圆柱投影 是圆柱投影的泛化。

¥Cylindrical projections project the sphere onto a containing cylinder, and then unroll the cylinder onto the plane. Pseudocylindrical projections are a generalization of cylindrical projections.

geoEquirectangular()

源代码 · 等距矩形（简易圆柱）投影。

geoMercator()

源代码 · 球面墨卡托投影。定义一个默认的 projection.clipExtent，将世界投影到一个正方形中，并裁剪到大约 ±85° 纬度。

¥Source · The spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.

geoTransverseMercator()

源代码 · 横轴球面墨卡托投影。定义一个默认的 projection.clipExtent，将世界投影到一个正方形中，并裁剪到大约 ±85° 纬度。

¥Source · The transverse spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.

geoEqualEarth()

源代码 · 平等地球投影，一种等面积投影，由 Bojan Šavrič 等人于 2018 年设计。

geoNaturalEarth1()

源代码 · 自然地球投影 是由 Tom Patterson 设计的伪圆柱投影。它既不是共形的也不是等面积的，但对于整个世界的小比例尺地图来说很吸引人。

¥Source · The Natural Earth projection is a pseudocylindrical projection designed by Tom Patterson. It is neither conformal nor equal-area, but appealing to the eye for small-scale maps of the whole world.
