#Bounds

Bounds describe an area which is defined by its north-eastern and south-western points.

All of phpgeo’s geometries except for the Coordindate class provide a getBounds() method via the GetBoundsTrait.

The Bounds class has a method to calculate the center point of the bounds object (works correctly for bounds that cross the dateline at 180/-180 degrees longitude too).

#Create Bounds for a given center point and distance to the corners

<?php

use Location\Factory\BoundsFactory;
use Location\Coordinate;

$bounds = BoundsFactory::expandFromCenterCoordinate(
    new Coordinate(52, 13),
    1000,
    new BearingSpherical()
);

The following image illustrates how the bounds (dashed line in red) are created:
