The Envitia team has been active within Open Geospatial Consortium (OGC) for many years participating on working groups and demonstration initiatives. Envitia took responsibility for architecting the Aviation Portrayal Service cluster, which involved 8 vendor’s technologies and a significant amount of information modelling. The result was an Aviation Portrayal Engineering report, with Envitia as the Editor, and contributions from many vendors. This document is published on the OGC website, and public videos illustrating a chosen scenario have been made available, http://www.opengeospatial.org/pub/www/ows7/index.html.
The aviation scenario, selected over a year ago for OWS-7 which, without irony, was a volcanic ash cloud disruption to air traffic, ended up providing a very real context for the capability illustrated. Events in Northern Europe in spring 2010 showed how serious such a disruption can be, and how important international interoperability between service providers, message brokers and application clients remains.
The new Envitia Feature Portrayal Service (FPS) can be seen displaying AIXM, WXXM and a WCS 4D weather data cube utilising specialist symbology and primitive attribution. The Feature Portrayal Service uses Style Layer Descriptors (SLD) stored in the registry to allow the Web Map Service (WMS) client to render the aviation and weather vector data. This approach allows data representations to be specified which are dependent upon rules as described in the SLD. These can be selected dynamically and therefore can allow powerful and customised visualisation.
