The Grid has many useful features. We can scan through space and time with it and get a visual image that we can use to steer the search. We have enough fine control that we can image each page in a stack of papers. On a more macro level, we can grab 3D models of solid objects. We also have the ability to capture video over time, not to just grab snapshots. Snapshots are useful, though, so we have the ability take those as well. On the cosmic scale, there are complex mathematical problems to be solved to locate the exact position and time to focus the grid. The Earth and solar system are moving through the universe, and we must know where to look to see a scene, such as the Dutch fleet off the Shetlands in early August 1652.
