We know that applications such as Google Maps, Google Earth and StreetView already acquiesce to regulations that require obscuration of government installations, private companies’ facilities in some cases, some brands, and private citizens faces and number plates—even as it works hard to decipher items like house numbers. In other words, technology is used to differentiate what we can see and not see, depending on the legal or ethical (or otherwise) standards of a particular place. For the most part, Google Maps, Google Earth and StreetView are forms of augmented reality. They digitally render reality with forms of markup, of contextual data, which adds to our perception of places. Except in the cases of blur, pixelation and, it could be argued, accidental presentation of various kinds of render ghosts—people and things only partly captured or partly presented, artifacts of digital accident or persistent memory. Some kind of determination is made that there are things present in reality that we can’t or shouldn’t see.
