Information concepts indicate the reference vocabulary and relations of an ArrestingSystemLocation with other concepts. 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 ArrestingSystemLocation 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 ArrestingSystemLocation 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 ArrestingSystemLocation is mapped in the AIXM 5.1 as feature ArrestingGear with property 'engageDevice' set to "EMAS".
Geometry
In the AIXM 5.1 the geometry of the ArrestingGear can be point, curve or polygon, but in case of this feature the correct geometry 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 : ArrestingSystemLocation
Time
Feature ArrestingGear[engageDevice='EMAS'] shall be established in accordance with coding rules and requirements listed in AIXM 5.1 Temporality Model.
AIXM 5.1 features
ArrestingGear is encoded to the AIXM 5.1 as feature ArrestingGear with property engageDevice set to 'EMAS'.
All associations are shown in the UML Diagram (see below).
