− | + | {{w|Optical resolution|Resolution}} is a term (roughly) representing the scale of the smallest identifiable feature in an image. In the context of terrestrial image mapping, this would correspond to the width of the square occupied by a single pixel in a terrestrial satellite image. In this strip, Randall points out that the resolution of images available to Google Earth has been improving at an exponential rate for the past decade. This is due to the improving quality of satellite imaging technology, as well as integration of additional data sources, such as aerial photography and street-level roaming cameras. Each tick in the scale represents a resolution improvement by three orders of magnitude. | |
− | + | The {{w|Planck length}} is a unit of length and in principle the shortest measurable length, thus making it effectively the "resolution" of our reality. It is around 1.6×10<sup>-35</sup> m, close to 10<sup>-20</sup> times the diameter of a proton. The comic shows how the current growth trend in resolution of Google Earth will hit the Planck length around the year 2100, even though such result is currently considered impossible to achieve. | |

It also refers to some heat that Google received before about it's vehicle mounted cameras being an invasion of privacy. Google came back saying that nothing the cameras pick up can't be seen by a pedestrian walking by. |
