Static method

• computeDistanceBetween(locationA, locationB)

  Returns the distance, in meters, between two LatLngs.

  Params	Type	Details
  locationA	ILatLng	origin
  locationB	ILatLng	destination

  :arrow_right: number

• computeOffset(from, distance, heading)

  Returns the LatLng resulting from moving a distance from an origin in the specified heading (expressed in degrees clockwise from north)

  Params	Type	Details
  from	ILatLng	origin
  distances	number	in meter
  heading	number	angle(clockwise)

  :arrow_right: LatLng

• computeOffsetOrigin(to, distance, heading)

  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.

  Params	Type	Details
  to	ILatLng	destination
  distances	number	in meter
  heading	number	angle(clockwise)

  :arrow_right: LatLng

• computeLength(path)

  Returns the length of the given path.

  Params	Type	Details
  path	ILatLng[] | BaseArrayClass<ILatLng>	a sequence of LatLngs

  :arrow_right: number

• computeArea(path)

  Returns the area of a closed path. The computed area uses the same units as the radius.

  Params	Type	Details
  path	ILatLng[] | BaseArrayClass<ILatLng>	a sequence of LatLngs

  :arrow_right: number

• computeSignedArea(path)

  Returns the signed area of a closed path. The signed area may be used to determine the orientation of the path.

  Params	Type	Details
  path	ILatLng[] | BaseArrayClass<ILatLng>	a sequence of LatLngs

  :arrow_right: number

• computeHeading(from, to)

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

  Params	Type	Details
  from	ILatLng	origin
  to	ILatLng	destination

  :arrow_right: number

• interpolate(from, to, fraction)

  Returns the LatLng which lies the given fraction of the way between the origin LatLng and the destination LatLng.

  Params	Type	Details
  from	ILatLng	origin
  to	ILatLng	destination
  fraction	number	A fraction of the distance to travel from 0.0 to 1.0 .
