Lengths and Angles

在不同的角度和长度单元之间转换并执行经度包装；转换沿地面表面的距离单位

On a perfect sphere, the distance between points on the surface of the sphere can be represented by angles. For spherical models of the Earth, Moon, and other planetary bodies, Mapping Toolbox™ allows spherical distance conversion between common units of angles and length.

Angles

Angle Representations and Angular Units
Use angles with Mapping Toolbox functions, convert between angle representations, and format angles as text.

Lengths

Length and Distance Units
球体上的电弧长度和距离的线性测量使用与平面上的单元相同，例如脚，米，里程和公里。

Spherical Distance

Distances on the Sphere
You can represent distances on the sphere using angles or linear arc lengths.
Relationship Between Points on Sphere
There are many ways to define the 2-D spatial relationship between two points on a perfect sphere, including azimuth, heading, spherical distance, linear distance, and range.
