  1. Digital Geospatial Information Working Group (DGIWG) AERONAUTICAL DATA HARMONIZATION Jeffrey Bell – NGA Aeronautical Harmonization Working Group Chair Briefing to AIXM Users Conference March 18, 2009 UNCLASSIFIED

  2. DGIWG SCOPE • DGIWG is a multi-national body responsible for geospatial standardization for the defense organizations of member nations. • DGIWG develops and maintains a suite of digital geospatial information (DGI) standards that foster the interchange, access and use of geographic information between the defense organizations of member nations. OGC

  3. WHAT WOULD YOU CALL THIS?? AIXM NATO DAFIF Aircraft Facility Aerodrome Airport Airstrip ICAO FAA AIP Land Aerodrome Airport/Heliport

  4. Aeronautical Information Harmonization Working Group (AIHWG) • Membership: 2006-Present • ICAO, EUROCONTROL • DGIWG REPS- US, IT, CA, GE, UK • Purpose • The group is tasked with investigating, and as far as is technically possible, removing the barriers to interoperability across all aeronautical information and products. • Objectives • Recommend aeronautical content and definitions for DGIWG Feature Data Dictionary (DFDD). • Setup mechanism to exchange, reconcile and improve definitions and data dictionaries • Identify, prioritize and complete the actions necessary to achieve improved levels of aeronautical data interoperability.

  5. AIHWG Progress TOR Formalized Jan 2007 Sept 2007 May 2006 Sept 2006 Mar 2008 June 2008 Nov 2007 Sept 2008 May 2007 COMPLETED REMAIN Navigation Aids Airspace Aerodrome Services Holding Instrument Procedures Aerodrome Features Military Training Routes Air Refueling Features: 75 Attributes: ~185 Enumerates:~950 Air Routes

  6. AIXM Connection • Using AIXM for basis for data dictionary integration. • Liaison with AIXM development team • Send all Terms and Definitions for AIXM development. • Redefined certain content and submitted proposals for development. • Defined all Enumerate values • Not historically done in AIXM

  7. DGIWG Registers DGIWG defines a number of specific lists of information elements that can be combined with the models in product specifications and application schema. - ISO 19110, 19126, 19135 • Feature and Attribute Data: https://www.dgiwg.org/FAD/ • Geographic features are real world phenomena associated with a location relative to the surface of the earth, about which data are collected, maintained, and disseminated. • Data Dictionary, Feature Catalog and Application Schema Registers • Metadata • DGIWG metadata standard profile registry that contains the register of ISO 19115 and ISO 19115-2 and any extensions identified in the DGIWG Metadata Profile of ISO 19139 for use by military coalitions • Geodetic Codes and Parameters, • Code Lists, and • Portrayal Symbols and Portrayal Rules.

  8. Hyperlinks to full internal documentation MS Excel Workbook Cross-linked entities(associations and inheritance) Full datatypespecifications

  9. Hyperlinks to full structure & content documentation,as well as management history for each item Dynamic Online Register

  10. What’s Next • Feature and Attribute Data • Register Aeronautical Feature Content in ISO19126 and ISO19135 conformant register (DGIWG Feature Data Dictionary). • https://www.dgiwg.org/FAD/ • Feedback deltas to ICAO, NATO, and interested Parties. • Set up permanent seat in DGIWG for aeronautical SME and AIXM

  11. What’s Next- Cont. • Application Schema • Register AIXM Feature Catalog and Application Schema with DGIWG – ISO19110 compliant. • Register a Metadata Profile- ISO19115 for Aeronautical Data <?xml version="1.0" encoding="ISO-8859-1" ?> - <schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:dafif="http://www.opengis.net/Faa/AIXM" xmlns:gml="http://www.opengis.net/gml/3.2" xmlns:sc="http://www.interactive-instruments.de/ShapeChange" elementFormDefault="qualified" targetNamespace="http://www.opengis.net/ows-4/Faa/AIXM" version="unknown"> - <annotation> <documentation>Version 5</documentation> </annotation> <import namespace="http://www.opengis.net/gml/3.2" schemaLocation

  12. What’s Next- Cont. • Symbology • Develop a portrayal register of aeronautical symbols for use with AIXM as well as other aeronautical data exchange formats based upon ICAO SARPS.
