Founded in 2007, OneGeology is a multinational initiative that aims to "make web-accessible the best available geological and other geoscience data worldwide at the best possible scales." It boasts participation from geological surveys and organizations in 118 countries (as of this write-up). One of OneGeology's main attractions is its Portal, which offers visitors an interactive geological map of the world that provides access to an immense catalog containing more than 750 datasets, maps, and web services. In addition to providing geological information, OneGeology strives to "improv[e] the understandability and interest in geology as well as just the availability of map data." Toward that end, the OneGeology eXtra section "is devoted to illustrating the many ways in which geology and geological maps play a fundamental part in all our lives." Here, readers will find resources intended primarily for general audiences on the intersections between geology and culture, examples of global geodiversity, and a collection of links from around the world that showcase how geological data can be used online. The OneGeology Kids section, intended for young rock collectors ages 10 and under, introduces readers to the basic geological ideas behind fossils, volcanoes, and more.
