Time stamp in UTC UTC month 0 2 UTC day of the month 1..31 28 UTC hours 0..23 23 UTC minutes 45 Timed circular notice This message can be broadcast with a timetoexpire of 0 to indicate that a region is known to not have a currently active notice. Original intent was endangered whale notification binary message. LNG terminal project. This is a draft. Please comment on the content of this message. J. Arroyo asked that this messages be made more general for circular regions that requires a timed notice. Proposed some areatypes here. Need help with these. Proposed transmission scheme for areatype=0 (right whale acoustic): A notice will be sent every 3 minutes for each buoy. Messages will be sent with timetoexpire of 0 when no acoustic detection has occured in the last 24 hours. When an acoustic detection, the system will send an separate broadcast for that buoy as soon as possible in addition to the normal 3 minute schedule. This needs to somehow be expressed. Is there a XML language for this? The (lat,lon,areatype) provide the key/id for each message. Any system is expected to overwrite any prior message message with a new message when it is received. This provide the mechanism to cancel out of date messages before they expire or extend the messages further into the future. Kurt envisions other messages to go with this that cover rectangular regions. Is there also need for poly lines defining things like large scale fronts in a separate message.
