Drone Complier Knowledge Base : User-defined Airspace

Adding user -defined airspace allows your organisation to display their own airspace zones on the airspace map. These are not visible to users from other organisations.

To use this feature, you will need to start with a correctly formatted geojson file for your airspace zone.

If you do not have one, you can easily create on using the online service here.

You now need to add some more details to your file, like the type of zone, altitudes, details, restrictions, hours of operations etc.

You can do this directly in the geojson file, or use the helper when you upload the file.

Below is a simple object produced using geojson.io. You can cut and past this into notepad or a similar plain text editor (don’t use Word etc as it ads additional characters), and save it to a file with the extension .geojson.

If you want to edit this file directly with the additional information to create an airspace zone, you need to add to the “properties” section.

Note: See step 5 of “Uploading Airspace” below where you can add or edit your parameters during file upload instead (or as well).
      "type": "Feature",
      "properties": {
            "NAME":"The name of the zone",
            "VERTICAL_LIMIT":"SFC - 1000",
            "ACTIVE_LEVEL":"3",
            "HOURS_OF_ACTIVITY":"H24",
            "DETAILS":"Additional details about the zone",
            "RESTRICTIONS":"Any restrictions that apply to the zone",
            "AUTHORITY":"The authority controlling the zone"
       },
      "geometry": {

Just change the text to suit your needs. Only NAME, VERTICAL_LIMIT and ACTIVE_LEVEL are required.

Note that geojson files must be in the correct format and quote marks and commas are important.

Data format:

NAME: This is the name of the zone that will appear in the warnings panel on the map.

VERTICAL_LIMIT: This defines the top and bottom altitude for the zone and needs to be in the correct format.
(bottom alt in feet) (reference – SFC or AMSL) – (top alt in feet) (reference SFC or AMSL)
So if your zone went from Surface (SFC) up to 1000 feet AMSL then you would enter the vertical limit as
“0 SFC – 1000 AMSL”

ACTIVE_LEVEL: A number between 1 and 4

  1. Information
  2. Danger
  3. Restricted
  4. Prohibited
HOURS_OF_ACTIVITY: You can type your own shorthand in here or use the NOTAM style abbreviations
  • W = MONDAY TO FRIDAY
  • E = WEEKENDS (SAT & SUN)
  • D = DAILY
  • H24 = CONTINUOUSLY
  • EXPH = EXCLUDING PUBLIC HOLIDAYS
  • HJ = SUNRISE TO SUNSET
  • HN = DURING HOURS OF DARKNESS
  • JO = MONDAY TO FRIDAY (EXC PUBLIC HOLIDAYS)
  • JF = SAT, SUN & PUBLIC HOLIDAYS
  • WS = MONDAY TO SATURDAY

DETAILS: Any additional details describing this zone.

RESTRICTIONS: Restrictions and / or instructions relating to this zone

AUTHORITY: The controlling authority for this zone.

Uploading Airspace:

The airspace geojson file is uploaded as a special type of document. This is done through the document centre.
1. Select Organisation > Documents

2. Click on the “Special Airspace” button to open the Airspace documents list.
3. Click on the  button and choose your geojson file.
4. Click the “Save” button.
5. Fill in any missing data that was not set up in parameters previously.
You should now be able to see the airspace you have uploaded.
