Built in units of measureΒΆ

Coordinates have many different types of unit e.g. latitudes are angles, but eastings are lengths.

There are also many different units in use across the world and across history, for instance most current mapping uses the metre for lengths, but older mapping often used feet or yards.

To avoid confusion about what any given number is intended to represent, all units in PHPCoord are typed as value objects.

Tip

All unit objects have helper methods ->getValue() and ->getUnitName(), and implement the Stringable interface
