Langscape, a project of the Maryland Language Science Center, is a set of tools to explore language diversity. The centerpiece of the project is an interactive map that lets users click on any geographic location to see the languages spoken there. Selecting a language allows users to access a growing variety of resources for that language. There is also a tool for the identification of languages based on (usually transliterated) texts.
