Method: Geocoder::Calculations#extract_coordinates

Defined in:
lib/geocoder/calculations.rb

#extract_coordinates(point) ⇒ Object

Takes an object which is a [lat,lon] array, a geocodable string, or an object that implements to_coordinates and returns a

lat,lon

array. Note that if a string is passed this may be a slow-

running method and may return nil.
