The EANS Aeronautical Information Feature Request Service enables the service consumer to request actual and future aeronautical feature data, such as aerodromes, airspaces, navigation aids, obstacles and ATS routes through a standardized SOAP-based request/response interface. The exact information needed by the service consumer can be specified in the information request based on feature name, location and/or time parameters. The information returned is in the form of an AIXM 5.1.1 message ensuring compliance with aeronautical information exchange standards.
Estonian Air Navigation Services (EANS, Lennuliiklusteeninduse Aktsiaselts) is a next generation air navigation services provider, headquartered in Tallinn, Estonia. We are state-owned public limited company under the jurisdiction Ministry of Economic Affairs and Communication of Republic of Estonia.
The EANS Aeronautical Information Feature Request Service provides access to aeronautical feature data stored in the EANS AIM database.

The service enables users to request aeronautical features stored in the EANS AIM database. These features, provided as structured digital objects, include airports and heliports, runways and landing areas, taxiways and aprons, airspace structures, navigation aids, flight procedures, waypoints, routes, and obstacles.
The service implements OGC Filter Encoding 2.0 Encoding Standard.
Service supports following logical operators: AND, OR, NOT.
The service supports following spatial operators: Within, DWithin, BBox.
Service supports following Comparison Operators: PropertyIsEqualTo-Operator, PropertyIsNotEqualTo-Operator, PropertyIsLessThan-Operator, PropertyIsGreaterThan-Operator, PropertyIsLessThanOrEqualTo-Operator, PropertyIsGreaterThanOrEqualTo-Operator, PropertyIsNull-Operator, PropertyIsNil-Operator, ContainsProperty-Operator.
Service supports following Reference Operators: References, ReferencedBy.
The service supports the retrieval of AIXM 5.1 features. All temporal operators described in OGC Web Feature Service (WFS) Temporality Extension (Doc nr OGC 12-027r3) are supported.
Restriction: the interpretation cannot be SNAPSHOT if temporal filters are used.
The attributes matchCase and matchAction are not supported and ignored.
Temporal filters on the valid time are supported but the interpretation cannot be SNAPSHOT if temporal filters are used.
When you sign up to use the service, your IP-address will be logged for analytics and behavioural purposes.
Users can retrieve baseline aeronautical data via the OGC Web Feature Service (WFS) 2.0 interface. The service does not perform automatic dataset publication; instead, all data resides in the AIM database and is made available upon explicit client request. Communication follows a SOAP-based protocol over HTTP, adhering to standard web service practices. Each client request must encapsulate the WFS operation within a SOAP envelope and transmit it to the service endpoint. The server processes the request and returns an AIXM Basic Message as the response, also embedded within a SOAP envelope and body, ensuring schema compliance with AIXM 5.1 and WFS-TE specifications. The interaction conforms to synchronous request–reply message exchange patterns as defined in the Message Exchange Patterns: Identification Guidelines, guaranteeing predictable behavior and interoperability across SWIM-compliant systems.
Incase of erroneous or invalid request an XML FaultMessage on the SOAP-level shall be generated indicating that an error has occurred.
The interface is used to group the operations offered by the OGC Web Feature Service 2.0 Interface Standard.
Returns XML metadata with information describing a WFS service provided by a server.
The GetFeature operation allows the retrieval of time slices. The GetFeature request will result in a¯GetFeatureResponseanswer containing a queryResult in the form of an XML file for every query defined in the request. The default feature version of the query responses is AIXM5.1.¯
The service Interface binding is compliant with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile.
The service shall use the network bindings of the SWIM TIYP IPv4 Secure Unicast.

This standard defines direct fine-grained access to geographic information at the feature and feature property level by specifying discovery, query, locking and transaction operations and operations to manage stored, parameterized query expressions. This standard covers 11 operations e.g. GetCapabilities (discovery operation). This Standard continues to be a reliable means to provide geospatial data to the web. However, the functional capabilities are now available in a more modern web API, OGC API â Features, and implementers are encouraged to use the newer Standard.
This standard is a jointly developed OGC and ISO TC/211 International Standard that describes an XML and Key Value Pairs (KVP ) encoding of a system neutral syntax for expressing projections, selection and sorting clauses collectively called a query expression.
This specification contains requirements for service descriptions, describing information services, in the context of System Wide Information Management (SWIM).
This specification contains requirements for the implementation of technical infrastructure supporting information exchanges in System Wide Information Management (SWIM). It enables technical interoperability by specifying standardised technical interfaces (e.g. protocols) and the capabilities required to enable a reliable, secure and efficient exchange of information.
