AsrnEdge encoding

Last updated: 2022 Oct 27

This section provides ‘AsrnEdge’ feature data encoding guidance.

General

AMD data encoding can start when the necessary geographic information, aeronautical information and basic knowledge regarding the structure of created feature is available. 

From the geographical point of view, the ASRNEdge represents a directional or bi-directional connection between nodes having an attached geometry which can be used for a graphical depiction of the taxi route. The key attributes are the longitude, latitude and the elevation in reference with WGS-84.

AMD encoding

AIXM 5.1

Feature AsrnEdge is out of scope of the AIXM 5.1 and can not be replaced or substituted by other feature. Therefore, it is available in the extension.

Geometry

The geometry of the AsrnEdge is curve encoded as object ElevatedCurve.

For more information regarding AIXM 5.1 Geometry encoding follow 'AIXM data coding'.

GML considerations:

AIXM 5.1 is based on GML. Hence, obtained geographical locations shall be transferred into a GML geometry object GeodesicString.


Time

Feature AsrnEdge shall be established in accordance with coding rules and requirements listed in AIXM 5.1 Temporality Model.

AIXM 5.1 features

AsrnEdge is encoded to the AIXM 5.1 extension as ASRNEdge features.

All associations are shown in the UML Diagram in Information definition for ASRN extension.
