Seems like a poor distinction to me - "identifiable" by what? A human eyeball, infra-red, multi-spectral analysis?
This would allow imaging of forests, fields, and streams, but not man-made objects like roads, bridges, dams, or the more navigable waters (might contain humans).
Perhaps the sponsor expects image-creators to blur out anything that might be a human or man-made object?
How would this affect the usage of self-driving cars? You could image a deer crossing the road, but not a human? (Note the prohibition is on image creation, not publication.)
