181 type-specific aircraft silhouettes, by RexKramer1
Read the complete GPL-3.0 license text
The map serves the originals with embedded metadata intact. Account cards serve standalone SVG outline derivatives that identify our modification and remain GPL-3.0.
14 generic category silhouettes, by Matthias Wirth (wiedehopf)
Read the complete GPL-2.0-or-later license text
Account-card outline derivatives remain GPL-2.0-or-later. "Or later" also permits treating them as GPLv3 when needed.

The map data behind the basemap
The rendered tiles the map draws
Elevation data for the live map's optional 3D terrain, fetched directly from Mapterhorn
The linked attribution page lists the underlying elevation datasets, their producers, and their licensing terms. Terrain data has source-specific terms, separate from Mapterhorn's software license.
The network you connect to
Not distributed to you, but named because feeders and clients interact with them directly — and one of them requires it.
Multilateration, originally developed by Oliver Jowett, with subsequent changes by TanerH and wiedehopf, and further maintained by adsb.lol
Network use counts as distribution under the AGPL. We run the adsb.lol fork unmodified, and that repository is the complete corresponding source for the build serving this network — which the server also tells every client on connect.
Mode S/ADS-B decoder and aggregator, by Matthias Wirth (wiedehopf)
Incorporates GPL-2.0-or-later and BSD-licensed code from the dump1090 lineage. Run unmodified. Credited by choice: it is the heart of the aircraft API, not a licence requirement.
