IWXXM SIGMET
The SIGMET collection includes:
- SIGMET,
- volcanic ash SIGMET,
- tropical cyclone SIGMET.
Current SIGMET collection
The EDR collection "sigmet" implements a "current" query as defined in MET3SG MET SWIM OGC EDR Community Guidance and its Appendix A: Definition of Latest, including the interpretation of SIGMET cancellations.
- Reports for an individual airspace can be queried using a /locations query using the ICAO code of the airspace.
- The API returns reports in the form of individual XML files stored in a ZIP archive.
- Temporal filtering is available via the
datetimeparameter; in this case, the query represents the question: "Which reports were current at the given datetime (interpreted relative to the issue time indicated in the report)?" - Stations can be filtered by spatial geometries (
/radius,/area,/cube,/corridorqueries). This is an IBL EDR feature, not covered by the MET3SG EDR Guidance document.
Example queries:
- Describe the collection:
https://swim.iblsoft.com:8444/edr/collections/sigmet - Current SIGMET reports in LZBB FIR:
https://swim.iblsoft.com:8444/edr/collections/sigmet/locations/LZBB - Multiple airspaces can be specified using a comma-separated list:
https://swim.iblsoft.com:8444/edr/collections/sigmet/locations/LDZO,LZBB
- Note that EDR implementations from other vendors or organisations might not support providing a list of locations.
Collection "sigmet-all"
See the introductory section on OGC EDR for details on how the "-all" collections interpret the query and the datetime parameter.
Examples:
- All SIGMETs for LZBB FIR whose validity interval includes the datetime:
https://swim.iblsoft.com:8444/edr/collections/sigmet-all/locations/LZBB?datetime={today:00:00} - SIGMET reports within a 100 km wide corridor of a flight path in a given time range:
