Picture Sky (2015 - Ongoing)

Crowdsourced Sky Images

In this project we create a crowdsourced image of the sky. Observers are positioned at GPS coordinates that form the points of a grid. At the moment of a flyover of either TERRA or AQUA satellite, they take photographs looking up at the sky. Their images are stitched together to form a single large image, equal and opposite to the one taken by the satellite. A smartphone app lets the observers self-organize at the times of satellite flyovers in any geolocation, coordinate the action, take the pictures in sync, and see the resulting crowdsourced image and the satellite image. The project explores mechanics of collective action and modes of knowledge production.
