Filtering

Filtering Capabilities OGC EDR

The EDR implementation builds on MET3SG community MET SWIM OGC EDR GUIDANCE. Additionally it supports OGC EDR filtering machanisms: cube query using a bbox parameter, area query with a polygon specified in coords parameter, radius query.

Filtering Capabilities AMQP

Simple filtering is achieved using the topic structure of the broker, which determines the type of data recieved. 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.

Source of Information

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

Technical

Service Monitoring

Monitoring Description

For AMQP subscriptions, regular heartbeat messages are sent to weather.aviation.SIGMET topic at approximately 60-second intervals. Arrival of the heartbeat message indicates that the main subsystems of the service are running.

The ACG IT components are montitored by 24/7 maintanance

Behaviour

Typical Request/Reply Behaviour

The typical behavior is following:

The client sends a request to the OGC EDR interface
The service replies with the appropriate HTTP response

Typical Data Distribution Behaviour

The service sends the data to subscribers when they are available and match their subscription using the AMQP protocol.

Typical Data Subscription Behaviour

For subscribing to data the consumer needs to contact the Service Provider and needs to request the credentials. After registration, the consumer is provided the endpoints both EDR and AMQP interfaces.
