Static Methods
computeArea(path[, radius])
Parameters:
Return Value: number
Returns the area of a closed path. The computed area uses the same units as the radius. The radius defaults to the Earth's radius in meters, in which case the area is in square meters.
computeDistanceBetween(from, to[, radius])
Parameters:
Return Value: number
Returns the distance, in meters, between two LatLngs. You can optionally specify a custom radius. The radius defaults to the radius of the Earth.
computeHeading(from, to)
Parameters:
Return Value: number
Returns the heading from one LatLng to another LatLng. Headings are expressed in degrees clockwise from North within the range [-180,180).
computeLength(path[, radius])
Parameters:
Return Value: number
Returns the length of the given path.
computeOffset(from, distance, heading[, radius])
Parameters:
- from: LatLng
- distance: number
- heading: number
- radius: number optional
Return Value: LatLng
Returns the LatLng resulting from moving a distance from an origin in the specified heading (expressed in degrees clockwise from north).
computeOffsetOrigin(to, distance, heading[, radius])
Parameters:
- to: LatLng
- distance: number
- heading: number
- radius: number optional
Return Value: LatLng
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.
computeSignedArea(loop[, radius])
Parameters:
Return Value: number
Returns the signed area of a closed path. The signed area may be used to determine the orientation of the path. The computed area uses the same units as the radius. The radius defaults to the Earth's radius in meters, in which case the area is in square meters.
interpolate(from, to, fraction)
Parameters:
Return Value: LatLng
Returns the LatLng which lies the given fraction of the way between the origin LatLng and the destination LatLng.
