WikiMapia allows any contributor to add a "tag" to any location by marking out a rectangle around the location and then providing a language (to be set as default), a title, and one of the predefined location types, such as "police station", "mountain", etc.  An optional note can be provided, as well as keyword tags, images, and embedded YouTube videos, which all appear on the place's information window. YouTube is a video sharing website where users can upload view and share Video clips YouTube was created in February 2005 by three former PayPal employees  For non-rectangular places, green bordered polygons can be added. In Geometry a polygon (ˈpɒlɨɡɒn ˈpɒliɡɒn is traditionally a plane figure that is bounded by a closed path or circuit
Location tagging is fully multi-lingual. Currently a total of 64 languages are supported, and 100% of the interface has been translated for 25 languages. 
Optional user accounts were introduced in October, 2006.  Since then, a system has been under development whereby users can rise in status. For instance, users can vote in favor or disfavor of other users' contributions, and there are three user levels explained in the Wikimapia FAQ. In October, 2007 a forum started for discussions by registered users.
Places added by new or unregistered users must be verified. Unverified places appear with a yellow outline and can be voted positive or negative on their description window. To be verified they must be at least 24 hours old and receive enough positive votes (for instance 2 positive and 0 negative).  Especially in some areas of the world with out-of-date or very expensive mapping, such as India, growth has been phenomenally rapid. However, this rapid growth has brought problems of its own with urban areas being covered with thousands of overlapping rectangles marking the position of private residences, but with no facility available in the WikiMapia interface to display places of public interest (as opposed to private houses, flats and apartments).
Basic tools for measuring distance and land area, and mapping IP addresses to locations are available from the menu at the top of the page.
Registered users can mark the route of roads using a series of segments and points. Once marked, these can be named and described in a similar manner to locations.
