This repository contains aircraft silhouette artwork and metadata used to build a spritesheet for Plane Watch.
Silhouettes are stored as SVG files and compiled into:
- spritesheet.png — a packed sheet of aircraft sprites
- spritesheet.json — metadata describing sprite positions and animation frames
These outputs are generated using the build_spritesheet tool.
Regular releases of this repository include prebuilt versions of:
spritesheet.pngspritesheet.json
These are intended for direct use in Plane Watch and other consumers without needing to build locally.
We’d love help expanding the aircraft library. If there’s a common aircraft type in your region that isn’t represented yet, please consider contributing a silhouette.
👉 All contribution guidelines (JSON format, SVG rules, and validation requirements) are documented in CONTRIBUTING.md.
Pull requests automatically run validation checks to ensure new files match the required formats.

Some SVG files in this repository may contain a "Reference Artwork" layer used during the creation of silhouettes. These reference images were sourced from publicly available materials such as aircraft three-view diagrams, manufacturer data sheets and brouchures.
These reference images are used solely as visual guides during the tracing process and are not part of the final silhouette artwork. The reference layers may be removed at any time and are not required for use of the silhouettes.
We do not claim ownership of any third-party reference images, and no rights to those materials are granted by this repository. The Creative Commons license applies only to the original silhouette artwork and associated metadata created for this project.
