SWIM Weather Demo-EDR-IWXXM SIGMET

IWXXM SIGMET

  • SIGMET data in IWXXM format
  • The API returns SIGMET reports in the form of individual XML files packed in a Zip archive

The iwxxm-sigmet EDR collection does not currently understand the concept of cancellations. For the given datetime requested, it will return all the SIGMETs whose validity period covers the specified datetime. The client must then find out whether any of the SIGMETs are cancellations that invalidate other SIGMETs in the list.

We are working on EDR collections that will properly understand the SIGMET life cycle and only return the SIGMETs that are really valid for the time or time interval the user is interested in.

Collection description

A formal description of the SIGMET data available in the collection: https://edr.swim.iblsoft.com/edr/collections/iwxxm-sigmet

Coordinate based queries

  1. All available SIGMET reports within 500 km range around Vienna airport:
    https://edr.swim.iblsoft.com/edr/collections/iwxxm-sigmet/radius?coords=POINT(16.56%2048.11)&within=500&within-units=km
  2. SIGMET reports within a 100 km wide corridor in a given time interval:
    https://edr.swim.iblsoft.com/edr/collections/iwxxm-sigmet/corridor?coords=LINESTRING(-6.25%2053.4,%200%2051.5,%202.3%2048.8,%2012.2%2041.8,%2033.6%2034.9)&corridor-width=200&width-units=km&datetime={today:-1:12:00/6h}
  3. All SIGMET reports in LZBB BRATISLAVA FIR: https://edr.swim.iblsoft.com/edr/collections/iwxxm-sigmet/locations/custom:SQLZBB

Please note that you need to prepend the 4-letter ICAO code of the airspace with custom:CC

CC is the two-letter WMO country code as used in the A1A2 part of the WMO message headings as defined in WMO Manual No. 386: Manual on the Global Telecommunication System:

  • Volume II – Regional Aspects
  • Annex II – Routing Catalogue (Table C1: Location Indicators by State).

The codes are listed also on https://community.wmo.int/en/table-c1.

In a future revision of the implementation of the EDR collection for SIGMETs this will no longer be necessary.
