Google Earth, yay...?

Similar to ColoradoGirl's blog, I initially thought of Google Earth when they mentioned satellite imaging technologies that stores all of this visual information (apparently Gmap is also powered by Google). So if something like this is then made available to any person with access to the internet, what do you think is the utility of these accessible satellite images?

The Critical Art Ensemble argues that the technology that collects visual information has a purpose of perpetuating the war machine in order for one to maintain power and place in the world. We can see that satellite technology has been used for military purposes. And for weather purposes. Then, it was accessible to the everyday consumer for navigational reasons. Now, if Google Earth suggests to the user to search for your house, buildings, and 3D terrain, are there other reasons why this is made for online access?
