Technical Design DecisionsIn the ISO19100 series
framework
  • Internationally developed standard for expressing
    geographical data
  • Features - Airports, Runways, Airspace
  • Metadata - Data originator, Status, Published
    Date
  • Temporality - Start and end dates
  • Geometry - Point, Line, Polygon
  • Helps us organize information for the
    aeronautical domain
  • Well-established
  • Geography Markup Language (GML)
  • Widely adopted and implemented by vendors and
    governments
  • Standards reduce barriers to adoption by vendors
    and governments

AIXM Structure and Application
  • AIXM provides the standard foundation for
    describing aeronautical information
  • Features Runway, En route Route, Airspace
  • Properties Valid time, Location
  • Data Types code list of airspace types
  • Metadata Data originator
  • AIXM can be used to build compliant application
    schemas
  • Enable real-world implementation
  • Digital NOTAMs
  • Procedure Design
  • Automated Charting
  • Enables maximum flexibility while remaining ISO
    compliant
  • Examples this afternoon and tomorrow

14
What is GML?
  • ISO exchange format for geographical features
    encoding
  • Based on XML Schema
  • Open GIS Consortium
  • Good industry adoption by Geographic
    InformationSystem (GIS) vendors
  • Commercial Off the Shelf Software

Temporality Model
  • Definition
  • A model that incorporates the concept of time
  • Key assertions
  • All features are temporal with start of life and
    end of life
  • Example, A new air traffic control sector
  • All features change over time
  • Example, A VOR is out of service for a day
  • AIXM Temporality Model
  • Relates features to the time extent in which they
    are valid
  • Provides various means to describe the time
    extent

16
Versions and Delta
  • Version The state of a feature and value of its
    properties over a time period between two
    changes.
  • Delta Difference between two consecutive
    versions.

17
Temporality Model (continued)
  • Operational changes are modeled as deltas
  • Deltas can be permanent or temporary
  • Permanent delta A set of properties that have
    changed or will change permanently. The permanent
    delta will result in a new baseline.
  • Baseline The state of a feature and all of the
    feature properties as a result of a permanent
    delta. The Baseline state of a feature also
    exists when the feature is initially created. The
    Baseline state lasts until the next permanent
    delta.
  • Temporary delta A set of values for one or more
    feature properties that are effective for a
    limited time. The result is a temporary change to
    an underlying feature version.
  • Version The state of a feature and all the
    feature properties during the time period between
    two changes.

This is a conceptual temporal model that can be
implemented in many ways
18
TemporalityConceptual Model
Imagine that AML Navaid undergoes an upgrade that
changes its frequency from 125 MHz to 132.5 MHz
  1. Schedule permanent change to coincide with update
    cycle
  2. Shutdown AML before the upgrade
  3. Perform the upgrade
  4. Start AML in test mode to evaluate change
