Joel Webber analyzed the DHTML behind the new Google Maps. It's nice to see a clean XHTML + CSS approach with absolute positioning and "console game" style, tile-based scrolling. Instead of using XMLHttp requests like in Google Suggest, there's a hidden Iframe which fires the parent's "load" function.Source: Google Blogoscoped
Joel's overview is a bit technical, but it and the over 100 comments to his post have some great info in them. Its pretty cool to understand how Google Maps works, or at least begin to understand. The coding behind it all seems pretty involved, I wonder if it will ever support KHTML/WebKit?
