Google Earth is a vision device that operates in the tension between two sets of eyes: vertical and horizontal. The vertical eye locates the observer outside the lived area in a privileged point, far from everyday life. With Google Earth, we have the globe to manipulate with our hands, in a radical disparity of the subject and world. But this world is a set of juxtaposed fragments of images, captured from above. The interval between the limit of resolution of each image when we descend into the soil and the approximate height of our eye on the ground level (1.70 m) is what we call Myopia Space of Google Earth, which is variable for each visited place. Myopia Index measures the public character of the Google Earth territory, since it is universally accessible but always controlled from a privileged place. The GeoEye, currently the commercial satellite capable of generating images with higher spatial resolution, is supported, firstly by the National Agency of the United States Geospatial Intelligence (NGA) and, secondly, by Google. The NGA will receive images from up to 43 cm spatial resolution, while Google does not exceed 50 cm in maximum resolution, due to a restriction imposed by the U.S. government. No gaze is neutral, much less the gaze of satellites that carry politically adjustable myopias. And if there are natural clouds, which hinder the satellites view while they pass, there are also the artificial clouds that freeze the landscape as compulsory vigilant glasses.
