SWIM Weather Demo-EDR-IWXXM SIGMET

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 datetime parameter; 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, /corridor queries). This is an IBL EDR feature, not covered by the MET3SG EDR Guidance document.

Example queries:

Collection "sigmet-all"

See the introductory section on OGC EDR for details on how the "-all" collections interpret the query and the datetime parameter.
