Geographic Data & Entities
The Wolfram Language has built-in access to extensive geographic data, including detailed worldwide maps and computable information on millions of geographic entities. Free-form linguistic input makes it easy to specify geographic entities and classes of entities (e.g. "counties in Illinois"). The Wolfram Language then provides an integrated symbolic representation for geographic constructs, together with detailed ontological classification and the ability to do sophisticated geodetic computations, as well as computations on socioeconomic and other data.
