UAS – Geo zones
Disclamer: changes to the website structure
Over the next few days, changes will be made to the structure of this website. Some sections may be removed or moved.
The aim of these changes is to improve clarity and provide easier access to published data packages and their purpose.
Thank you for your understanding.
Remarks on published data in ED-318 format
Published data in ED-318 format are intended for geoawareness functions in unmanned systems. Due to technical limitations of most target devices, the data has been generalized – the geometry of the boundaries has been simplified so that the file size complies with the limits of the ED-318 format and the limits of unmanned system software. The exact and legally binding boundaries of the geographical zones are available in the .geojson reference files in the table below. The data is published in two ZIP files:
For categories A1/A2
For category A3
Contains all binding layers, including the HOP (densely populated area) layer, which is binding for categories A1/A2. Does not contain the Settled Area layer, which is only intended for category A3.
Contains all mandatory layers, including the Settled Area layer, which is mandatory for category A3. Does not contain the HOP (densely populated area) layer, which is only intended for categories A1/A2.
The files are divided into numbered tiles (see image below), with each tile containing an overlap of 2.3 km. The published data serves only as a technical representation for specific purposes and is not intended as a substitute for reference data. For pre-flight preparation and flight planning, we recommend using the DroneMap, which displays the current and accurate zone boundaries. Data is updated regularly in line with AIRAC cycles. Each release is archived and may be further refined based on technological developments.
