Show NAAD and NOAA public alerts on a map
Mapping works as a standalone application and follows the Open Broadcaster module framework to allow integration into the observer Platform.
The National Alert Aggregation & Dissemination (NAAD) GeoRSS feed provides realtime Active Public Safety Messages (CAP-CP) alerts issued by Authorized Government Agencies for Canada (see tech info for specs). The feed may be found at http://rss.naad-adna.pelmorex.com/.
Conversion of the GeoRSS feed into geoJSON makes use of Andrew Harvey's excellent prototype
The National Oceanic & Atmospheric Administration (NOAA) provides a WMS map service shows where a warning of hazardous weather or hydrologic event is occurring, imminent or likely.
