Digital Geospatial Information Working Group (DGIWG)

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.

• 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.

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 RegistersDGIWG 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.

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

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.
