Behaviour

Feature Access: Geospatial NOTAM information is exposed as geospatial feature collections of points and polygons. Point features represent NOTAM without explicit spatial extent; polygon features represent NOTAM with defined geographic areas or airspace volumes.

Data Retrieval: Clients can query and retrieve NOTAM features using spatial and attribute criteria. Spatial filters include bounding-box and polygon-based queries. Attribute filters include NOTAM identifier, aerodrome/FIR, validity times, Q-code, and operational categories.

Operations: Standard operations include:

  • Querying feature collections (filtering by geometry and attributes)

  • Retrieving service and layer metadata (capabilities/description endpoint)

  • Accessing update timestamps from auxiliary resources (where available)

Responses are delivered in machine-readable, structured formats (e.g., JSON/GeoJSON) suitable for integration into operational systems and visualization tools.

Standard Compliance: The service follows a REST-based geospatial interface.

Interaction Pattern: Synchronous request–response: clients send HTTP requests to the designated endpoints; the service processes the request and returns structured geospatial data in the response.
