This paper presents a technology capable of enabling the creation of a diffuse, calibrated vision-sensor network from the wealth of socially generated geo-referenced imagery, freely available on the Internet. Through the implementation of an accurate image registration system, based on image processing, terrain modelling and subsequent correlation, we will demonstrate how images taken by the public can potentially be used as a mean to gather environmental information from a unique, ground-level viewpoint normally denied non-terrestrial sensors (consider vertical or overhanging cliffs). Moreover, we will also show this registration technology can be used to synthesize new views using sections of photos taken from a variety of places and times.
