Attempts of capturing that have been plagued with deficincies and currently policy seems to now be to completely open this process up to the world and the end users. To facilitate that Google has recently announced the launch of Google Building Maker, a fun and simple tool for creating buildings for Google Earth.
Building Maker is cross between Google Maps and a gigantic bin of building blocks. Basically, you pick a building and construct a model of it using aerial photos and simple 3D shapes – both of which Google provides. When you're done the model is examined. If it looks right, and if a better model doesn't already exist, it is added it to the 3D Buildings layer in Google Earth. You can make a whole building in a few minutes.
For now, you can choose to make buildings in any of about 50 cities. Building Maker is an online tool, and it runs entirely in your web browser (Google Chrome, Firefox, Safari, Internet Explorer etc.). Models you create with Building Maker "live" in the Google 3D Warehouse (a giant, online repository of 3D models). You can use Google Sketchup to edit or otherwise modify anything you make with Building Maker.
A cool initiative by Google and based on admirable business model. Check out the vid above to see how Building Maker works.
