I learned from last class that Google provides map information to everyone who wants to integrate Google Map API and Virtual Earth API. So we can easily call these APIs to web site. I know map information should be huge data. However map was displayed within a short time. Especially I was surprised when I saw 3D map and current traffic information. I realized how useful it is.

Here I have one question. If I make a web application for business, can I integrate Google Map API and Virtual Earth API for free ?
