Convert between different angle and length units and
perform longitude wrapping; convert units of distances along the surface
of the Earth

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.

**Working with Angles: Units and Representations**

Angles specify the position and distance of geospatial objects.

**Angles as Binary and Formatted Numbers**

Angles are traditionally formatted in decimal degrees for mapping applications.

**Working with Length and Distance Units**

Linear measurements of lengths on spheroids use the same units they do on the plane.

**Compute Conversion Ratio Between Units of Length**

This example shows how to create a conversion factor
for many different units of length using the `unitsratio`

function.

**Working with Distances on the Sphere**

Distances on the sphere are represented by both angles and arc lengths.

**Positions, Azimuths, Headings, Distances, Length, and Ranges**

Several angular and linear quantities express the distance between two points on a sphere.

**Convert from Linear Measurements to Spherical Measurements**

This example shows how to convert distances along the surface of the Earth from linear units to angular units.
