API

SphericalUtil::computeHeading, _(*3)

Returns the heading from one LatLng to another LatLng. Headings are expressed in degrees clockwise from North within the range [-180,180)., _(*4)

SphericalUtil::computeOffset, _(*5)

Returns the LatLng resulting from moving a distance from an origin in the specified heading (expressed in degrees clockwise from north)., _(*6)

SphericalUtil::computeOffsetOrigin, _(*7)

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., _(*8)

SphericalUtil::interpolate, _(*9)

Returns the LatLng which lies the given fraction of the way between the origin LatLng and the destination LatLng., _(*10)

SphericalUtil::computeAngleBetween, _(*11)

Returns the angle between two LatLngs, in radians. This is the same as the distance on the unit sphere., _(*12)

SphericalUtil::computeDistanceBetween, _(*13)

Returns the distance between two LatLngs, in meters., _(*14)

SphericalUtil::computeLength, _(*15)

Returns the length of the given $path, in meters, on Earth., _(*16)

SphericalUtil::computeArea, _(*17)

Returns the area of a closed $path on Earth., _(*18)

SphericalUtil::computeSignedArea, _(*19)

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., _(*20)
