Last week I wanted to see what's there around me and how the things around me look like. You may not agree with me over what I did, but I think that it's a nice way to get what I wanted.
In fact, I went discovering some magnificent satellite pictures of the earth! The following sites proved to be very attractive:
Wikimapia is based on Google Maps. But here, registered users may say "here is my home", "this is a garden", "that's a football pitch", etc. by defining areas, tagging them, and describing the places in their own words!
For the more enthusiastic, for whom 2D is not so exciting, 3D satellite images come handy. Google Earth is certainly well known. NASA World Wind is another service that's as enjoyable.
Happy discovering :)
