Notice: The National Geospatial-Intelligence Agency (NGA) has removed
DAFIF™, FLIP, and ECHUM data from the NGA public web site effective
October 1, 2006. Department of Defense (DoD) customers are able to
access DAFIF™, FLIP information, and ECHUM by accessing the NGA's web
site on the NIPRNet. The NGA NIPRNet site, in accordance with a number
of DoD directives, is Public Key Enabled (PKE); meaning that the site is
encrypted using the DoD Public Key Infrastructure (PKI).
