Wikimapia.org - Let's Describe The Whole World

WikiMapia is an online map and satellite imaging resource that combines Google Maps with a wiki system, allowing users to add information (in the form of a note) to any location on Earth. WikiMapia is unrelated to Wikipedia but the website states that it was “inspired by Wikipedia”.

Using WikiMapia is fairly simple. WikiMapia allows you to add a "Hotspot" to any map by marking out a rectangle which is wiki-linked to a note providing information about the locality. The note may be in any of 64 languages currently supported, and may be modified by any contributor, as in a wiki. The possibility of roads marking will be introduced soon. You can also add private places like personal homes. If you have Google Earth installed you may see WikiMapia places by clicking on the WikiMapia data layer for Google Earth. Another awesome feature is that YouTube videos can be added to WikiMapia locations. Adding YouTube video URLs will automatically embed them into the place information page along with a link to the video’s page at YouTube. Like this place? You can help WikiMapia submitting WikiMapia to news sites and forums, adding new interesting places and modifying place information where needed, adding information in English, where is only another language.
