Figure 7-1. To find time windows of series that might intersect with the shaded circle, we only have
to check segments that intersect with the six squares A-F. These squares involve considerably more
area than we need to search, but in this case, only three segments having no intersection with the
circle would have to be scanned because they intersect squares A-F. This means that we need only
scan a small part of the total data in the time series database.
