Filtering Capabilities (EDR)

Filtering is exposed through OGC API - EDR query parameters and collections, including spatial, temporal, and parameter subsetting of IWXXM-derived attributes.
Filtering Capabilities (AMQP)

Topic-based filtering is available through the brokerâs topic hierarchy. AMQP 1.0 filters (e.g., ICAO location identifier) can be applied via standard message headers as defined by the message schema.

The service provider ensures that the data offered within this service is created by LHMS, a REGULATED_METEOROLOGICAL_SERVICE_PROVIDER.

Name

SIGMET (Significant Meteorological Information)

Definition
