PaintedCenterline encoding

This section provides ‘PaintedCenterline’ 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, several points of the outer border of the PaintedCenterline 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 RunwayMarking is 'Curve'. The definition of Line/Curve can be found in the Table A1-9 Data types of the Aeronautical Data Catalogue.

AMD encoding

AIXM 5.1

ED-99 feature PaintedCenterline is mapped to the the AIXM 5.1 as feature RunwayMarking with property Location set to "CL".

Geometry

In the AIXM 5.1 the geometry of the RunwayMarking can be point, curve or polygon, but in case of this feature the right geometry 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 RunwayMarking shall be established in accordance with coding rules and requirements listed in AIXM 5.1 Temporality Model.

AIXM 5.1 features

PaintedCenterline is encoded to the AIXM 5.1 as feature RunwayMarking with property markingLocation set to 'CL'.

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