Data concept:

Information concepts indicate the reference vocabulary and relations of an RunwayDisplacedArea with other concepts for operational experts. Data concepts indicate the reference features and properties for service architects, information/data architects and system implementers.

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, several points of the outer border of the RunwayDisplacedArea need to be captured. The key attributes are the longitude, latitude in reference with WGS-84 and the elevation of each captured point. In the next part the process of converting the geographical information into the GML form thus into geometry information is described.

Based on Aeronatical Data Catalogue the required type of geometry for feature RunwayElement is 'Polygon'. The definition of Polygon can be found in the Table A1-9 Data types of the Aeronautical Data Catalogue.

AMD encoding

AIXM 5.1

ED-99 feature RunwayDisplacedArea is mapped to the AIXM 5.1 as feature RunwayElement with property Type set to "DISPLACED".

Geometry

In the AIXM 5.1 the geometry of the RunwayElement is polygon encoded as object ElevatedSurface.

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 PolygonPatch.

Figure 1 : RunwayDisplacedArea

Time

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

AIXM 5.1 features

RunwayDisplacedArea is encoded to the AIXM 5.1 as RunwayElement feature.

All associations are shown in the UML Diagram (see below).

Note
This is a ficticious example. No feature was present at the aerodrome used.

The following AMD properties are not covered in the AIXM 5.1. coding example: vres, hres, integr, lvo. These are covered by an AIXM 5.1. extension.
