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
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
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:
