You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: land_parcels_json_exchanger.rb
    path of file: ./repos/ekylibre/app/exchangers/ekylibre
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Ekylibre
  # Import a GeoJSON file (as FeatureCollection) with `name` and `numbe
    
      def find_cultivable_zone(shape)
        # check if current cluster cover or overlap an existing cultivable zone
        shapes_over_zone = CultivableZone.shape_covering(shape, 0.02)
        return shapes_over_zone if shapes_over_zone.any?

        CultivableZone.shape_matching(shape, 0.02)
      end
