Synthetic flight data.

Photoreal rendered flight video with perfect ground-truth telemetry, from 3D reconstructions of real terrain we surveyed ourselves. Built for teams training and evaluating vision-based navigation, visual odometry, and geolocation — systems that must keep working when GPS does not.

  • Exact per-frame pose — not estimated
  • Georeferenced WGS84 + local ENU
  • Calibrated camera model per clip
  • Nordic & western-European terrain

What a clip looks like.

Six frames from six clips in the current catalogue, exactly as they ship — the flight HUD is burned into the video so a frame is readable on its own, and the telemetry file beside it is the authoritative record. Nordic and Irish terrain, 14 to 122 m above ground, in orbit, rise and cruise-dive trajectories.

Rendered aerial frame over dense Finnish conifer forest with a flight HUD showing latitude, longitude, altitude and height above ground.

finland_e — rise reveal

Finland · 63–122 m AGL · real coordinates

Rendered aerial frame over a Finnish forest clearing with a flight HUD.

finland_g — rise reveal

Finland · 57–103 m AGL · real coordinates

Rendered aerial frame orbiting a forestry plantation and its access road, with a flight HUD.

coolquane — orbit

Ireland · 39–48 m AGL · datum-shifted coordinates

Rendered aerial frame over cut farmland showing crop lines, with a flight HUD.

barnane — rise reveal

Ireland · 22–66 m AGL · datum-shifted coordinates

Rendered frame diving towards a rocky coastal inlet, with a flight HUD.

nohoval — cruise and dive

Ireland · 14–49 m AGL · datum-shifted coordinates

Rendered frame cruising over a plantation edge and forest track, with a flight HUD.

glanworth_c — cruise and dive

Ireland · 15–60 m AGL · datum-shifted coordinates

Synthetic — every frame here is rendered from a georeferenced 3D Gaussian-splat reconstruction of a site we surveyed by drone. The terrain is real and was measured; the flight through it was not flown. Reconstruction quality varies with the survey behind it, and the catalogue carries a quality score per clip so you can see which is which before you buy.

One line per video frame, verbatim from finland_e — 270 records for a nine-second clip. The camera block repeats on every record so a single line is self-contained; it is abbreviated above.

What ships in every bundle.

One directory per clip: the rendered video, a telemetry file with one record per video frame, and a manifest with the camera model, provenance, quality metrics, and checksums — plus the full format specification. Position, attitude (quaternion and Euler), velocity, altitude above ground, and intrinsics use documented aerospace conventions, so ingestion is a morning's work, not a project.

  • Because the camera is simulated, the pose track is exact — no GNSS error, no IMU drift, no annotation queues.
  • Every clip passes automated quality control, including an optical-flow check that the pixels move exactly as the telemetry says they should.
  • Terrain comes from photorealistic 3D reconstruction of real surveyed sites — forest, farmland, trails, and buildings, at 15–120 m above ground.

On selected sites, absolute coordinates carry a fixed datum offset for landowner privacy; relative motion, attitude, and height above ground are always true, and each file declares its policy. Real-coordinate delivery is available under contract.
