module GoogleMapsService::Apis
# Performs requests to the Google Maps Elevation API.
module Elevation
# Provides elevation data for locations provided on the surface of the
# earth, including depth locations on the ocean floor (which return negative
# values).

# @example Single point elevation
# results = client.elevation({latitude: 40.714728, longitude: -73.998672})
#
# @example Multiple points elevation
# locations = [[40.714728, -73.998672], [-34.397, 150.644]]
# results = client.elevation(locations)
#
# @param [Array] locations A single latitude/longitude hash, or an array of
# latitude/longitude hash from which you wish to calculate
# elevation data.
#
# @return [Array] Array of elevation data responses

#
# @param [String, Array] path A encoded polyline string, or a list of
# latitude/longitude pairs from which you wish to calculate

# @param [Integer] samples The number of sample points along a path for which to
# return elevation data.

# @return [Array] Array of elevation data responses
