SADIS API

The SADIS API, introduced in February 2023, provides access to higher resolution WAFS data sets from ICAO Annex 3, Amendment 82. It will replace SADIS FTP, which retires in 2028.

The SADIS API is:

SWIM compliant and conforms to the EUROCONTROL SWIM yellow Profile standards
Published in the EUROCONTROL SWIM Registry 
Uses the Open Geospatial Consortium (OGC) Environmental DATA Retrieval (EDR) API framework

To access the SADIS API, users must:

Register by emailing the SADIS Manager and completing the form provided (this includes existing SADIS FTP users).
Review the service summary and the SADIS API Services user terms and conditions.
Accept the SADIS API Licence Agreement.

Data available on the SADIS API

The data sets are summarised below. Full details can be found in the SADIS API User guide which details the full set of WAFS gridded data available.
