1. Presented February 21, 2006 at NOAA RSS, Podcast/Vodcast, Blog Workshop by Eliot Christian, United States Geological Survey Using RSS for Public Warnings

2. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 2  The Challenge of Public Warning  Common Alerting Protocol (CAP) and Really Simple Syndication (RSS)  CAP + RSS Examples at USGS  Geospatial Coordinates in RSS Using RSS for Public Warning

3. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 3 Collaborative actions are necessary to assure that standards-based, all-media, all-hazards public warning becomes an essential infrastructure component available to all societies worldwide. http://www.isoc.org/challenge The Challenge of Public Warning

4. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 4  All-media: All available communications media (from broadcast down to individual targeting) are needed to get timely and appropriate warnings to everyone who needs them, and to only those who need them  All-hazards: Public warning systems should be in routine use for all hazards, not only for rare events such as earthquakes and tsunami, but for severe weather, fire, and other threats. The Challenge of Public Warning Goal and Requirements

6. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 6 Alert Sender filtering and routing processes Target Audience Common Alerting Protocol CAP message

7. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 7 ! Alert Sender Common Alerting Protocol Filtering and Routing Processes ! Target Audience sending processes receiving processes filtering and routing processes Filtering and Routing Process Examples: Filtering of warning messages Routing of warning messages per communications model Conversion, translation, formatting per specific target device (network routers, PCs, PDAs, telephones, televisions, highway signs, sirens, etc)

8. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 8 Common Alerting Protocol CAP Filtering and Routing Criteria  Date/Time  Geographic Area (polygon, circle, geographic codes)  Status (Actual, Exercise, System, Test)  Scope (Public, Restricted, Private)  Type (Alert, Update, Cancel, Ack, Error)

9. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 9 Common Alerting Protocol CAP Filtering and Routing Criteria  Event Categories (Geo, Met, Safety, Security, Rescue, Fire, Health, Env, Transport, Infra, Other)  Urgency: Timeframe for responsive action (Immediate, Expected, Future, Past, Unknown)  Severity: Level of threat to life or property (Extreme, Severe, Moderate, Minor, Unknown)  Certainty: Probability of occurrence (Very Likely, Likely, Possible, Unlikely, Unknown)

10. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 10 Why Really Simple Syndication (RSS)?  Target recipients of messages may not have continuous communications connectivity  News readers allow the user to set the refresh interval differently for each RSS news feed  Messages for weather, earthquakes, etc. are being offered as an RSS (Really Simple Syndication) news feed

11. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 11 Combining CAP with RSS  The CAP standard specifies that each message has a unique identifier, date/time stamp, and short human-readable descriptor ("headline")  To support geospatial visualization, it is important to place WGS-84 coordinates (especially point and polygon) directly in the RSS feed, at RSS channel/item level  For internationalization, item "title" value should be a concatenation of fixed CAP values

14. RSS and CAP Feeds from USGS

15. February 21, 2006NOAA RSS, Podcast/Vodcast, Blog Workshop 15 Use of RSS in USGS USGS public website offers several RSS feeds:  Recent Earthquakes (w/ CAP)  Latest USGS News Releases  Latest Landslide Hazard Alerts (w/ CAP)  Latest Volcano Hazard Alerts (w/ CAP)  National Cooperative Geologic Mapping Program News  Geography – What’s New
