Map of Florida counties showing the number of Aircraft Warning Service observation posts in each county. The map differentiates between posts that had been assigned and those that had actually been established. The map notes that 211 of the state's 881 assigned observation posts were at existing fire towers. The original county map on which this information was inscribed was developed by the Florida State Planning Board.
