    Retrieves a list of supported geo locations.
    Countries are listed first, and continents are listed last. If Amazon Route 53 supports subdivisions for a country (for example, states or provinces), the subdivisions for that country are listed in alphabetical order immediately after the corresponding country.

    :type StartContinentCode: string
    :param StartContinentCode: The code for the continent with which you want to start listing locations that Amazon Route 53 supports for geolocation. If Amazon Route 53 has already returned a page or more of results, if IsTruncated is true, and if NextContinentCode from the previous response has a value, enter that value in StartContinentCode to return the next page of results.
            Include StartContinentCode only if you want to list continents. Don't include StartContinentCode when you're listing countries or countries with their subdivisions.
            

    :type StartCountryCode: string
    :param StartCountryCode: The code for the country with which you want to start listing locations that Amazon Route 53 supports for geolocation. If Amazon Route 53 has already returned a page or more of results, if IsTruncated is true , and if NextCountryCode from the previous response has a value, enter that value in StartCountryCode to return the next page of results.
            Amazon Route 53 uses the two-letter country codes that are specified in ISO standard 3166-1 alpha-2 .
            

    :type StartSubdivisionCode: string
    :param StartSubdivisionCode: The code for the subdivision (for example, state or province) with which you want to start listing locations that Amazon Route 53 supports for geolocation. If Amazon Route 53 has already returned a page or more of results, if IsTruncated is true , and if NextSubdivisionCode from the previous response has a value, enter that value in StartSubdivisionCode to return the next page of results.
            To list subdivisions of a country, you must include both StartCountryCode and StartSubdivisionCode .
            

    :type MaxItems: string
    :param MaxItems: (Optional) The maximum number of geolocations to be included in the response body for this request. If more than MaxItems geolocations remain to be listed, then the value of the IsTruncated element in the response is true .
