Subject: RE: OGC, WFS, and CAP demonstration

To add to the list of implementations of CAP - but with a twist: Integrated into a complete EM workflow that also incorporates the use of OGC interface standards. This from a soon to be released short article on a GEOSS demonstration at IGARRS (International Geosciences and Remote Sensing Symposium) in July in Korea:

The scenario began with a George Mason University (GMU) client accessing a Common Alerting Protocol (CAP) message as a Geography Markup Language (GML) document from an Intergraph server that implemented OGC's OpenGIS Web Feature Server Specification® (WFS). Landsat imagery was provided by the NASA-JPL WMS Global Mosaic.


The Common Alerting Protocol (CAP), from OASIS, is a simple but general format for exchanging all-hazard emergency alerts and public warnings over networks. The OpenGIS® Geography Markup Language (GML) Specification®, (all the OpenGIS Specifications are products of the international consensus process managed by OGC), defines a data encoding in XML – an XML "namespace" – for geographic data and its attributes. The OpenGIS Web Feature Server Specification® (WFS) describes data manipulation operations on OGC Simple Features (e.g., points, lines, and polygons) so that servers and clients can communicate at the feature level.



I will send the article once it is edited and approved.
