OWS-8 Aviation Work Areas

Advancement of AIXM

• • • • • Maturation of delivery, filtering and update of AIXM via WFS Continued development of reusable tools (Validation + refactoring) Benchmarking of compression and binary XML techniques Interoperable styling and portrayal Validation of AIXM metadata and GML profiles 2.

Advancement of Aviation Architecture

• Advancement of Event Architecture, including validation of Digital NOTAM Event Specification • • Support for AIXM Authoritative Data Source requirements Leveraging of DataLink concepts and requirements 3.

Advancement of WXXM and Weather Concepts

• • • • Review and validation of WXXM schemas Encoding rep4D/5D weather forecast and radar datasets On-demand CRS definitions and transformations Distributed approach for managing UoM

1. Advancement of AIXM

• • • • • • Addressing the conflict between AIXM temporality model and OGC Feature Model • Guidance on using AIXM over WFS 2.0 (or WFS Aviation Profile) • Changes to WFS 2.0, FE 2.0 and/or AIXM 5.1

Dealing with estimated or unknown end of validity for attribute values in AIXM 5.1

• Dealing with FE 2.0 behavior with indeterminate is heavily used in AIXM features Further exploring and testing SNAPSHOT queries support Solving the issue of filtering AIXM events by property • Supporting filtering of AIXM events Leveraging WFS 2.0 capabilities • WFS 2.0 Stored Queries (creation, loading and deletion) • WFS 2.0 Additional Objects (simplifying xlink referencing and resolving) Implementing/validating metadata and GML profiles identified by Aviation DWG

2. Advancement of Aviation Architecture

• • Advancing Event Architecture • General features • Multiple sources and types of events and data changes • • Use of WFS-T for posting AIXM events to AIXM database Different delivery protocols (Atom/AtomPub, WS-Eventing, Broadcasting, Transmission of events at pre-defined intervals or batch transmission) • Registration & subscription lifecycle management • Accuracy of subscription filters, dynamic spatial filters, automatic termination/renewal of subscriptions, use of Stored Queries, Event Channels (ad-hoc channels, best practices) • Validating and advancing The Digital NOTAM Event Spec • • • Testing and enhancing Event Schema Implementing and testing scenarios described in Spec including creating data Implementing in ISO Schematron the business rules defined in the Spec Supporting Authoritative AIXM Data Source requirements • • • WFS-T and AIXM 5.1

Metadata for transactions Authentication/Authorization (granularity of data update constraints) • Data Integrity/validation

3. Advancement of WXXM and Weather Concepts

• • • • Review and validation of WXXM schemas Recommendations for encoding 4D/5D weather radar forecasts and datasets • Representing data that can be served and queried via WCS 2.0

Support for on-demand CRS definitions and transformations • How can a WCS client request a specific CRS when there’s no EPSG (or other) code associated with it?

• How can a WCS 2.0 server formally advertise the capability to support arbitrary CRS as opposed to a fixed number of CRSs Recommendations for distributed approach for managing UoMs • Sustainable, extensible and simple ways • Keeping in mind that new units of measures will likely depend on existing unites of measures

OWS-8 Aviation Scenarios

• Dispatch and Planning (Continued from OWS-7) – Testing new weather concepts – Using real-time weather to increase situational awareness • As part of OWS-8, such accurate and up-to-date weather conditions will be accessible via a WCS 2.0, that will be developed to 1) securely ingest weather radar data supplied by a major international carrier with routes over the pacific basin, and (2) convert the source data into WXXM 1.1. The weather WCS will endeavor to support the emerging Data Link concept as defined by the RTCA SC-206 wherever possible. • Validation of AIXM Authoritative Data Source Architecture – Update of AIXM features via WFS-T – Capture of metadata – Basic user authentication (identity and role) – Basic access control – Validation of data according to business rules • Digital NOTAM Event Spec Scenarios – Activation/deactivation of published ATS space – Creation of ad-hoc SAA, ATS airspace, etc – Route portion closure or opening – New/Withdrawn obstacle – Aerodrome/Runway/Taxiway closure – Airport service contamination • Probabilistic Weather in Decision Making – Demonstrate the potential of using probabilistic information in weather data in decision-support applications. The NOAA Meteorological Development Lab (MDL) will provide all the weather data (via WFS and WCS) •
