    :format =>'json',

    :results_per_page => 100,

    :lat => ENV['LAT'].to_f || -34.6096717,

    :lon => ENV['LON'].to_f || -58.429007

}

wikimapia = Wikimapia::Geometries::API.new(config)

page = 1

first_request = wikimapia.fetch(:page => page)

abort "Error in first_request" if not first_request

total_results = first_request[:found].to_i

polygons = first_request[:places]

logger.info "Initial request completed. Total results: #{total_results}"

while polygons.count < total_results do

  page += 1

  request = wikimapia.fetch(:page => page)

  abort "Error in HTTP request ##{config[:page]}" if not request

  polygons += request[:places]

  logger.info "Request ##{page} succeeded"
