Grid size, distance & zoom
How the grid spacing controls coverage and the search zoom.
Grid size (e.g. 13×13) sets how many points are scanned. Distance sets the spacing between points: tighter spacing = a smaller, more detailed area; wider spacing = a larger area, less detail.
The Google Maps search zoom is derived automatically from your grid spacing, so each point reflects a realistic local view. You can see the resulting zoom per saved configuration in Grid Configs.
