1) Moving electronic messages by location information rather than by internet address.
2) Hardware or software mechanisms to accomplish this.
EDXL-DE (Emergency Data Exchange Language - Distribution Element) is a message format standard produced by the OASIS standards body. It is designed as a "envelope" to contain other messages, and contains the kind of information needed to route the message to the intended destination. In this case the intended destination is the set of emergency responders interested in a particular physical location, and concerned with the events there.
A jurisdiction is an area under the control of particular legal authority or government. In a "federated democracy" like the United States of America there are many jurisdictions with different budgets, elected officials and laws. Emergency responders work for a jurisdiction and are limited by it.
For emergency responders in a jurisdiction to recieve messages about any events in their jurisdiction, but only those they are responsible for, they need to subscribe to those events in that area. They must do so by role as well, such as police, fire or ambulance. This is important because in an emergency there can be a overwhelming number of confusing messages which can impair operations. Some mechanism must filter out the messages that each function in each jurisdiction needs to see.
This idea of an official subscribing to information related to his or her role in their physical area of responsibility is called subscription by jurisdiction. For this to be possible you need geospatial routing. EDXL-DE is the message envelope standard that supports these concepts.
