Shows the availability of historical maps over each decade, for the current location and view level. Simply click on a decade to view the available map. Currently selected decade is highlighted in red Decades in blue mean there are maps available for that decade. Where there is more than one map available in a decade, the earliest map is shown. Decades in grey mean there are no historical maps available for that decade, at that location and map view. Your decade selection is retained when you move around and zoom in/out..
