(FILES) A picture taken on November 15, 2014 shows a part of the gas storage site operated by French natural gas transmission system operator Terega in Lussagnet, southwestern France. The 3D image of the factory reveals every pipe, every tap, every valve. Rather like the Google street view navigation service, which constantly maps the earth. This actual image is then analysed by artificial intelligence, which compares it with the existing data contained in the factory's 'official plan'. It then detects anything that doesn't match.
