radarcontrol.io uses data and services from the following sources. We are grateful to all the contributors and maintainers who make this possible.
Data sources
Aircraft performance data
Aircraft type definitions, performance characteristics, and specifications are sourced from the openscope project:
- Project: openscope, github
- License: MIT License
- Usage: Aircraft performance data for 140+ aircraft types including speeds, climb rates, turn rates, and wake categories
- Files:
/data/aircraft/*.json
Vector map data
Geographic vector data for land masses, coastlines, lakes, rivers, roads, airports, and administrative boundaries is sourced from Natural Earth:
- Project: Natural Earth
- License: Public Domain
- Usage: Vector data rendered as custom map tiles for the radar display background
Natural Earth Attribution:
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.
Natural Earth data is in the public domain and free for use in any type of project.
