I'm not a lawyer, but per Feist v. Rural, facts cannot be copyrighted in the United States. Collections of facts may be eligible for copyright, but it requires authorship, and hinges on the creativity of presentation (the author must select which facts to include, how to present them, etc.) but the facts within the collection are not entitled to copyright protection. If this collection was generated automatically by accessing the Google API, it would probably not qualify for copyright protection based on a lack of creativity in its creation.
