SERVICE_STANDARD

This International Standard specifies the behaviour of a service that produces spatially referenced maps dynamically from geographic information. It specifies operations to retrieve a description of the maps offered by a server to retrieve a map, and to query a server about features displayed on a map. This International Standard is applicable to pictorial renderings of maps in a graphical format; it is not applicable to retrieval of actual feature data or coverage data values.

Standardised SWIM service design for an AMAN Sequence Service. This standardised service design follows the specification documents for service descriptions as provided by EUROCONTROL. Together with them, it can be used as a basis to implement SWIM Service instances.

The temporality extension has been developed in order to align the OGC WFS 2.0 and FES 2.0 standards with the AIXM 5.1.1 Temporality Concept. It allows retrieving data in AIXM 5.1.1 format via OGC WFS 2.0 requests.

This International Standard specifies the behaviour of a service that provides transactions on and access to geographic features in a manner independent of the underlying data store. It specifies discovery operations, query operations, locking operations, transaction operations and operations to manage stored parameterized query expressions.

The information scope offered by the service supports the requirements of the Digital NOTAM Specification.

The GML Profile for aeronautical data is limited to 2D elements and includes only the features necessary for encoding geometries of type point, line/curve and polygon/surface (outer boundaries only). The following components of GML are out of scope for the AIXM GML Profile: Topology, Linear Referencing, Coverages. This additional GML component necessary to the ISO 19139 (gco /basicTypes.xsd), which is imported in the GML and AIXM metadata, needs additional types. These types are not included in this profile.

In accordance with the ICAO Global Air Navigation Plan (GANP) (Doc 9750) https://www4.icao.int/ganpportal/, the VAAC London QVA API has been built in accordance with the System Wide Information Management (SWIM) requirements.

The downloaded IWXXM data (.xml) will return all the information within a single file. This will adhere to the schema IWXXM Schematrons published here: https://schemas.wmo.int/iwxxm/

Note: up until late November 2025 the 2025-2R1 schematron is used, and when the final candidate version published (version 2025-2) the system will be updated to reflect it. If further changes are made to the schematrons by WMO further updates will be made, potentially coordinated with the other VAAC’s and you will be notified in advance that it will be changing.
