Within OWS-8, the aim was to further evaluate the effectiveness of the basic mandatory WFS 2.0 operations and full filter encoding FE 2.0 to retrieve AIXM 5.1 data for the
various flight planning and dispatch scenarios identified.
7.1.1.3 Data available via the components
The OWS-8 consolidated database consists of data containing BASELINE and TEMPDELTA timeslices from the following sources:
EANS: the EANS AIXM 5.1 was made accessible via the Comsoft WFS. Some
of the feature types relevant for the scenario were harvested and loaded into the consolidated database using GO Loader.
EurocontrolLFV FAA Airports GIS data and AMDB Obstacles data: these
data provided for use within OWS-6 and 7 were published from the original project databases as AIXM 5.1 and loaded into the consolidated database using
GO Loader.
Eurocontrol Digital Snowtam Trial 2011: A global dataset of AirportHeliport
AIXM 5.1 features were harvested on an ad hoc basis from the WFS established for the Digital Snowtam trial.
FAA NASR Subscriber data: pre-operational data feed providing access to
AIXM 5.0 SAA messages updated every 56 days inline with the AIRAC cycle. These were loaded into initially into an SAA 5.0 database then published out as
AIXM 5.1 and loaded into the consolidated database using GO Loader.
FAA SAMS SUA Data feed: operational data feed providing access to SAA
Activation schedules .csv updated every minute.
Test Events: a set of example test events were created to support the various
scenarios that were inserted into the consolidated database via the WFS-T 2.0
7.1.1.4 Accomplishments
Several key accomplishments were developed within OWS-8 within the data maintenance and publication architecture developed by Snowflake:
Consolidated data from multiple sources, published using different AIXM 5.1 extension schemas into a single authoritative database and provided access to
these data via the WFS 2.0 and Event Publisher Extended the database to include some example reverse associations for
