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

2. Digital Geospatial Information Working Group (DGIWG) 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

4. Digital Geospatial Information Working Group (DGIWG) 4 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. Aeronautical Information Harmonization Working Group (AIHWG)

6. Digital Geospatial Information Working Group (DGIWG) 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. Digital Geospatial Information Working Group (DGIWG) 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.

9. Digital Geospatial Information Working Group (DGIWG) 9 Dynamic Online Register Hyperlinks to full structure & content documentation, as well as management history for each item

10. Digital Geospatial Information Working Group (DGIWG) 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. Digital Geospatial Information Working Group (DGIWG) 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 - Version 5 <import namespace="http://www.opengis.net/gml/3.2" schemaLocation

12. Digital Geospatial Information Working Group (DGIWG) 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.
