This section:

  • includes the correspondences between elements in the different models that cover the needs of aerodrome mappings
  • elaborates on the data encoding of AMD features and properties in accordance with revised ICAO Annex 15 and new PANS-AIM (ICAO Doc 10066), applicable European regulations and industry standards e.g. EUROCAE ER-009
  • provides examples of AIXM 5.1.1. encoding

Limitations

on correspondence

The correspondence tables supporting material alone will not guarantee that an ED-99/DO-272 compliant Aerodrome Mapping Database is created. This can only be done by applying

  • the data product specification rules and
  • the complete functional and geometrical constraints

within ED-99/DO-272 and its normative encoding found in ED-119/DO-291.

In addition, where calculations or geometrical mergings are required, visual verification of the result will be required.

In some cases, additional steps are required by the implementer. For example:

  • AIXM 5.1.1 allows the use of the geometrical curves and geodesics. ED-99/DO-272 only allows line-strings. Therefore the curve will need to be transformed into a line-string. Details on such transformations are out of the scope of this site.
  • The AMDB Default values will need to be added to the AMDB where the AIXM 5.1.1 data is missing elements that are mandatory in AMDB.


Info
titleBefore you begin...

Before you begin you should know:

  • Documents
    • EUROCAE ED99 and RTCA DO-272 are equivalent specifications. This is also true of ED-119 and DO-291.
    • The latest version of the “User Requirements for Aerodrome Mapping Information” is ED-99D/DO-272D.
    • ED-119C/DO-291C "Interchange Standards for Terrain, Obstacle, and Aerodrome Mapping Data" is also used on this page to provide e.g. enumeration. It contains the encoding to be used when realising ED-99/DO-272.
  • Models
    • The latest version of AIXM is AIXM 5.1.1.
    • AMXM is a schema that can be used to exchange aerodrome mapping data. The latest version is AMXM 2.0.0.
    • The AIRM is a vocabulary that is used for semantic interoperability.
  • Correspondences
    • The correspondence tables follow a given structure. See: How to read ...the supporting material.
    • Not everything has a correspondence so extensions are required. See AIXM 5.1.1 extensions.

    • The correspondences alone will not guarantee that an ED-99 compliant Aerodrome Mapping Database is created. This can only be done by applying the data product specification rules and the complete functional and geometrical constraints within ED-99 and ED-119. See Limitations to the correspondences.
