message is essential for validation purposes. As a result Snowflake Software prototyped a digital NOTAM enrichment service; the enrichment of digital NOTAM messages
includes the retrieval of relevant baseline data that corresponds to the affected feature.
AIXM 5.1 baseline data and digital NOTAM data were loaded using commercial off-the- shelf software into a PostgreSQL PostGIS database. The enrichment process is invoked
on load of digital NOTAMs, using internal processing logic; the loaded digital NOTAMs are enriched by the appropriate AIXM baseline data. Once internal processing of AIXM
baseline data is complete, digital NOTAMs accompanied with associated AIXM baseline data can be retrieved from the WFS service. The spatial closure of digital NOTAMs is
also calculated for spatial querying purposes.
WFS stored queries with predefined filter parameters for Testbed 11 scenario use cases were created to enable the request of an enriched digital NOTAM. Figure 6 illustrates the
digital NOTAM enrichment service process flow.
