Been playing with Googlemaps

Been playing with googlemaps and rails. The first step is geo-coding the address to Lat long coordinates.

Here is my first play code

require 'net/http'
require 'uri'
require 'rubygems'
require 'builder'

addrs = [ "1600+Amphitheatre+Parkway,+Mountain+View,+CA",
          "1159 Gympie Rd Aspley QLD 4034 ",
          "14 Morayfield Rd Caboolture QLD 4510 ",
          "521 Ipswich Rd Annerley QLD 4103 "
        ]

placemarkbase = 'List'
placemarks = Hash.new

xml = Builder::XmlMarkup.new(:target => $stdout, :indent => 4)

geocoder = "http://maps.google.com/maps/geo?q="
output = "&output=csv"
apikey = "&key=### insert your googlemaps token here ###"

counter = 0
addrs.each do |addr|
    request = geocoder + addr + output + apikey
    sleep 2.0
    url = URI.escape(request)
    resp = Net::HTTP.get_response(URI.parse(url))
    fields = resp.body.split(',')
    placemarks[placemarkbase + counter.to_s] = [addr,fields[3],fields[2]]
    counter += 1
end

kml = { 'xmlns' => 'http://earth.google.com/kml/2.2'}
xml.instruct! :xml, :version => "1.1", :encoding => "US-ASCII"
kml.each do |key,value|
    xml.kml(:xmlns => value) do
        xml.Document do
            placemarks.each do |key, array|
                xml.Placemark do
                    xml.name(array[0])
                    xml.address(array[0])
                    xml.description(placemarkbase)
                    xml.Point do
                        str = array[1].to_s + "," + array[2].to_s + "," + 0.to_s
                        xml.coordinates(str)
                    end
                end
            end
        end
    end
end
