Tutorial — Geolocation from photos
Skill: geolocation-verification-specialist
Time: ~30–90 minutes
Goal
Narrow where a photo was taken using public visual clues — with explicit uncertainty.
Steps
- List fixed objects: signage language, road markings, vegetation, architecture, power poles.
- Check EXIF only if you have lawful possession of the file; strip before republishing others’ images.
- Use sun angle / shadows only as a weak hint unless you can calibrate date/time.
- Compare candidates in Street-level imagery where licensed and lawful.
- State a confidence band (city vs neighborhood vs country).
- If used in a published claim, label (estimated) per ITI inferred-data policy.
Pitfalls
- Lookalike cities and franchise architecture.
- Deepfakes and synthetic backgrounds — pair with provenance checks.
