The search engine behind Terrapattern is based on an Artificial Intelligence (AI) and will learn, i.e.g improve, over time. You can for example select a church and then, Terrapattern will show all visually similar objects. For now, Terrapattern is only available for selected case studies, ie. Pittsburgh, San Francisco, New York, Detroit, Miami and Berlin!
