EDIS Emergency Digital Information Service

California has enhanced its emergency information dissemination capability with Digital communications techniques. It is called EDIS -- the Emergency Digital Information Service. Borne out of the impetus created by the Loma Prieta earthquake, EDIS is a very inexpensive way to provide a hard copy printout of emergency information bulletins from the National Weather Service, the River Forecast Center, the U.S. Geological Survey, the National Earthquake Information Center (in Golden, CO), the U. S. Forest Service and the State Office of Emergency Services. All a broadcast station or other site requires is a radio receiver, a "dumb" (terminal Node controller) terminal or computer, and a printer. All messages are transmitted over a 100-mile radius from Northern California's Mt. Diablo in the "ANPA 1312" standard for high speed news Data services recommended by the Radio-Television News Directors Association. Each message in the ANPA format includes standardized codes to identify its source, urgency, type, length and destination. All messages including the phrases "EBS ACTIVATION REQUESTED" or "IMMEDIATE BROADCAST REQUESTED" are marked with a special selector code for special handling by the receiving computers. EDIS serves the greater LOS Angeles area through the cooperation of ENN -- the Electronic News Network. This area is served by transmitters on Mt. Wilson. San Diego is served from Mt. Palomar.
