DAFIF was publicly available until October 2006 through the Internet, however it was closed to public access because 'increased numbers of foreign source providers are claiming intellectual property rights or are forewarning NGA that they intend to copyright their source'. Currently only Federal and State government agencies, authorized government contractors and Department of Defense

At the time of the announcement, the NGA did not say who the 'foreign source providers' were. It was subsequently revealed that the Australia
