Description

Additional values are introduced for the types of VerticalStructure to allow for more precise data coding and alleviating information loss, when regularly value OTHER is used.

Note: This CP replaces the previously approved AIXM-522.

Rationale for change

See https://aixmccb.atlassian.net/browse/AIXM-280, https://aixmccb.atlassian.net/browse/AIXM-441, https://aixmccb.atlassian.net/browse/AIXM-568

It was identified that the current list of values of data type CodeVerticalStructureType may be insufficient.

The majority of the VerticalStructure.type(s) included in this proposal adds the missing types that can be referenced to the ICAO Annex 4 symbols or RTCA DO-291C types. It was also identified that some of the proposed obstacles types are frequently used in the available OBS DS as plain text OTHER:

The change proposal also includes changes to several definitions, where there exist preferences to indicate an obstacle type as OTHER: (e.g. “OTHER:MAST” vs “POLE”) due to different terminology (e.g AmE vs. BrE). These could be avoided by including the synonym in the definition.

Despite the fact that this change proposal tries to resolve a large part of these identified issues, it will certainly not satisfy all data providers/users. Further clarifications are expected in future versions of AIXM.

The table below provides the overview of justification for the values included in this change proposal:

[FWD_MAP_1:1] Data mapping is possible and no data loss occurs when data is exchanged from a system (A) that uses AIXM 5.1.1 for output towards a system (B) that uses AIXM 5.2 for input.

[BWD_MAP_1:1] Data mapping is possible and no data loss occurs when data is exchanged from a system (B) that uses AIXM 5.2 for output towards a system (A) that uses AIXM 5.1.1 for input.
