Filtering Capabilities (EDR)

Filtering is exposed through OGC API - EDR query parameters and collections, including spatial, temporal, and parameter subsetting of IWXXM-derived attributes (e.g., aerodrome ICAO designator, validity period).
Filtering Capabilities (AMQP)

Simple filtering is achieved using the topic structure of the broker, which determines the type of data received. AMQP SQL-like syntax for filters applied to AMQP application properties can be also used by the service consumer to further filter the data received.

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