Look for humanPhotos: preserve the original
Use the original JPG from the card or an export that preserves EXIF and XMP. Editing and messaging services may remove GPS. Capture a test at a known location, load the photo and check the drone marker. A DJI filename alone does not prove coordinates exist. Refer to your model’s manual for settings and available data.
Video: enable and keep subtitles
If your device supports video SRT subtitles, enable their recording in video settings. The option name varies by DJI Fly or other app version. Keep the video and matching-name SRT together. Import both into Look for human. Flight tracks and frame GPS come from recorded subtitles, not from guessing the landscape.
What enables a person estimate
A photo needs GPS, RelativeAltitude, gimbal pitch and direction, plus camera field of view or a supported focal-length value. The camera must point sufficiently downwards. The app projects the box centre onto flat ground and shows uncertainty. Terrain relief and telemetry errors can substantially displace the estimate.
When data is incomplete
SRT with position but without camera angles provides the drone position at detection time. No GPS means the finding cannot be placed on the map. DJI Fly WHEP/RTMP does not automatically supply telemetry here. Always tell field teams which type of position you are reporting. Do not fill gaps by assumption.
