WikiMapia or Wikimapia is an open-content collaborative mapping project that aims to mark and describe all geographical objects in the world. It combines an interactive web map with a geographically-referenced wiki system. As of early 2013, the project's website claimed that registered users and guests have already marked over 20,000,000 objects. The user-generated content added by users is supposedly available under a Creative Commons licenses Share-Alike license through both a web application and an API.
According to their website, "WikiMapia is an open-content collaborative mapping project, aimed at marking all geographical objects in the world and providing a useful description of them." Also "The goal of Wikimapia is to create and maintain a free, complete, multilingual and up-to-date map of the whole world. Wikimapia intends to contain detailed information about every place on Earth."
Wikimapia was launched at 24 of May in 2006 by two Russian Internet entrepreneurs Alexandre Koriakine and Evgeniy Saveliev.
