This silent video presents raw screen recordings of the Terrapattern system in use.
Terrapattern is an interface for finding "more like this, please" in satellite photos. Simply click an interesting spot on Terrapattern's map, and it will find other locations that look similar.
Terrapattern can be briefly described as "a visual search engine for satellite imagery", "similar-image search for satellite photos", or "a prototype for visual query-by-example in satellite imagery". For more information, see terrapattern.com.
