Passenger Pigeon is a project/concept for collecting aerial imagery from passenger plane windows with handheld digital cameras. To make a map, just take photos out the window of your commercial flight. Then use [MapKnitter.org](https://mapknitter.org) to align the images with a map as soon as you land. ###Examples### * Utah (shown below): http://publiclaboratory.org/notes/eustatic/5-10-2012/hills-have-acne-passenger-pigeon-photos-drill-sites-out-west * Manhattan/Brooklyn: ###Tips for photographers### * point the camera as straight downwards as possible * hold the camera as stably as you can - brace it against the window * try not to sit behind the wing, where the engine exhaust blurs the air * take note of where the photos are, if you anticipate difficulty in placing them on a map later ###Advanced### Some Public Lab folks have done multispectral imaging from a plane window -- see http://publiclaboratory.org/passenger-pigeon for near-infrared
