Terrapattern is the first open-source tool to perform "similar-image searches"
for satellite photos. It's become a first iteration of what could be an
essential digital weapon for humanitarian agencies, environmentalists, and
civic activists. Already, satellite images have become a key tool in managing
displaced population camps. But though satellite imagery from private
companies is now plentiful, finding patterns in it is impossible without
heavy-duty computer algorithms to analyze it.
