2.1 Web Feature Service
Data was loaded, validated, transformed and corrected from multiple sources This effort included splitting the data into two Web Feature Service WFS
instances, one for North American data and one for Middle-Northern Europe data Calculation of airspace extents in full 2.5D, including composite airspaces
unions, intersections and subtractions, support for altitude queries including calculation of extents of non-spatial feature types runways, taxiways and aprons,
and support for spatial filtering of non-spatial feature types.
2.2 Registry Service
The OWS-9 Aviation Registry was used to host resources shared between multiple OGC services e.g. ISO metadata pertaining to datasets common to multiple Web Feature
Service implementations, styling information shared between multiple Feature Portrayal Service implementations, and ISO Service metadata describing the Services deployed in
OWS-9. The efficient retrieval of metadata task was also implemented using the Aviation Registry by designing queries to retrieve only the relevant excerpts of the metadata
desired by clients.
2.3 Event Service
Compared to the Event Services ES used in the previous OGC test beds, major improvements were been implemented during OWS-9, particularly features summarized
under the term “Advanced filtering functionality.” These included “Event Service Update Intervals”, “Stored Filters”, “AIXM Features as Geometry Operands”, “Spatial
Filtering of Non-spatial Features”, “Simple Altitude Queries” as well as “Selective Metadata Retrieval”.
2.4 Web Processing Service
Web Processing Service profiles were implemented to support Electronic Pre-Flight Information Briefing ePIB generation and geometry processing, including calculation of
topological relations between two AIXM 5.1 features in ellipsoidal space. Supported topological relations included INTERSECTS, DISJOINT, EQUALS, TOUCHES,
CROSSES, OVERLAPS, CONTAINS, WITHIN, COVERS, COVERED_BY.
2.5 Data Management Service
