Detections

Line segments representing detected contrails.

Detections provide observational contrail detection data only and aren't mapped to specific flights. However, they can be filtered by time ranges, bounding box and satellite origins.

It is important to note that data consistency cannot be guaranteed for detections as detection models may be upgraded or data backfills may occur between reads.

Data format

Detections are in GeoJSON format containing a FeatureCollection:
