WikiMapia

Wikimapia is a multilingual open-content collaborative map, where anyone can create place tags and share their knowledge. Our goal is to describe the whole world by compiling as much useful information about all geographical objects as possible, organize it and provide free access to our data for public domain. It should be plain and simple so that anyone without prior experience with maps could get along, and the descriptions should be as apprehensible and interesting as if you asked a local. One of the main characteristics of Wikimapia is that it's constantly changing, striving to be always up to date and correct and to collect more and more information from all the sources at hand. How does it work? Wikimapia data is wholly made by Internet volunteers, who contribute to the project on their free will. Marking places, adding descriptions provided with proof links, giving them appropriate categories and uploading photos to Wikimapia let people easily share information about the world with their friends or publicly. While contributing, user gains experience and gets access to more advanced tools (e.g., linear features for marking roads, rivers, railroads and ferry routes). A user can also share Wikimapia data to blogs, sites and social networks, as there is an option to put the map on your page.
