Standard Data Format (SDF) - SOS Feature of Interest Demonstration

Fetching Tsunami Features of Interest...
 

The NDBC Sensor Observation Service (SOS) now includes features of interest (FOI) for Deep-ocean Assessment and Reporting of Tsunamis (DART®) tsunami events. There are two types of FOIs:

  1. A single station event returns water level data for a single DART® station from ten days prior to the event trigger time to seven days after event trigger time. These FOIs are referenced with a urn of urn:ioos:event:tsunami::ttttttt:sssss:dddddddd, where tttttttt represnts the type of event, e.g., "false", "manual", or "geophysical", sssss represents the station ID (21413) and dddddddd represents the event trigger date time in YYYYMMDDHHMMSS format (20090114152400). For this event, the urn would read: urn:ioos:event:tsunami::manual:20090114152400_21413.
  2. An FOI triggered by a seismic event may have one or more stations defined for it. This type of event returns the water level data for those stations from ten days before the earliest trigger time in the group to seven days past the latest trigger time. The urn for these FOIs is formatted as urn:ioos:event:tsunami::tttttttt:eeeee, where tttttttt represents te type of event ("geophysical") and eeeee represents the event name, typically a date (YYYYMMDD) and area such as 20090319_tonga. For this event, the urn would read: urn:ioos:event:tsunami::geophysical:20090319_tonga.

These DART® event FOIs are also categorized as follows:

  1. Geophysical - caused by some geophysical activity.
  2. Manual - manually triggered.
  3. False - false event.
