I think this electronic navigator is very cool. It's not just a map, it makes life easier by providing shortest path from origin to destination. With estimated time of travel too. And the best thing is, free.

This electronic map has a very large database with enormous amount of information. If you need any direction to any site in a metro like surabaya, believe me, you won't get lost. But, unfortunately, when you need to roam suburb areas you might need some luck. Local tukang ojek and tukang becak are the better navigator.

I think it would be nice if travelers could contribute information to map's database like people contribute articles to the wiki.
