A 311 photo shows long, east-facing shadows while the complainant says it was “noon at City Hall.” How should the analyst use that lighting?
Select an answer to reveal the explanation.
Short Explanation
Noon sun sits high; long sideways shadows mean the clock or the place is off. Treat lighting as a sniff test, not a courtroom sundial diploma. If the story and the shadows fight, flag the mismatch.
Full Explanation
At PORP fundamentals depth, sun angle and shadow direction are consistency checks against a claimed time and location, not a substitute for professional photogrammetry. Long east-facing shadows conflict with a local-noon, open-plaza claim and should be recorded as unresolved. Analysts should not invert imagery to force a match or treat 311 captions as self-authenticating. Report the conflict and keep working other geo clues.
