Google just released Street View for some cities in my country. Are there some way to find out if a city is available on Street View? Is there a list of cities or a search tool?
You can find this information here: http://en.wikipedia.org/wiki/Google_Street_View#Areas_included
This question on Google's support pages - In which parts of the world is Street View available? has a map showing current coverage.
