Web-Mapping Applications with Google API

I recently upgraded my Google web-mapping application in the
contact section to the map API Version 2 which exposes nearly the entire interface to customization to enjoy a higher quality in terms of service tools that can introduce custom location icons, location coordinates and metadata providing greater user-interactivity by performing asynchronous network requests with Javascript and XML (AJAX).
Well, nothing special about that, but everything depends on precision and quality of service and I experienced that the digital-imagery improved a lot since last year. Combining Gmaps with other sophisticated services could turn it into a giant well working global business system over the next years. I'm thinking of geo products that will become more and more popular and will enable businesses to build services like geo-tracking or just view a data source in a geographic context.
It's part of a
web vision of a world in 3D to conduct buisiness on a level of interaction we have never experienced before.
