This library provides classes and functions for the computation of geometric data on the surface of the Earth. Code ported from the Google Maps API.
Require this package with composer using the following command:
composer require javidalpe/spherical-geometrySphericalUtil::computeHeading
Returns the heading from one LatLng to another LatLng. Headings are expressed in degrees clockwise from North within the range [-180,180).
SphericalUtil::computeOffset
Returns the LatLng resulting from moving a distance from an origin in the specified heading (expressed in degrees clockwise from north).
SphericalUtil::computeOffsetOrigin
Returns the location of origin when provided with a LatLng destination, meters travelled and original heading. Headings are expressed in degrees clockwise from North. This function returns null when no solution is available.
SphericalUtil::interpolate
Returns the LatLng which lies the given fraction of the way between the origin LatLng and the destination LatLng.
SphericalUtil::computeAngleBetween
Returns the angle between two LatLngs, in radians. This is the same as the distance on the unit sphere.
SphericalUtil::computeDistanceBetween
Returns the distance between two LatLngs, in meters.
SphericalUtil::computeLength
Returns the length of the given $path, in meters, on Earth.
SphericalUtil::computeArea
Returns the area of a closed $path on Earth.
SphericalUtil::computeSignedArea
Returns the signed area of a closed path on Earth. The sign of the area may be used to determine the orientation of the path. "inside" is the surface that does not contain the South Pole.
