ParkingStandLocation encoding

This section provides ‘ParkingStandLocation’ 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 ParkingStandLocation represents a designated area on an apron intended to be used for parking an aircraft. . This position is represented by one point and only this point shall be measured. The key attributes are the longitude, latitude and the elevation in reference with WGS-84. 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 ParkingStandLocation is 'Point'. The definition of geometry type Point can be found in the Table A1-9 Data types of the Aeronautical Data Catalogue.

AMD encoding

AIXM 5.1

ED-99 feature ParkingStandLocation is mapped to the AIXM 5.1 as feature AircraftStand.

Geometry

In the AIXM 5.1 the geometry of the RunwayCentrelinePoint is point encoded as object ElevatedPoint.

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 location shall be transferred into a GML geometry object Point.

Time

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

AIXM 5.1 features

ParkingStandLocation is encoded to the AIXM 5.1 as AircraftStand feature.

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