A method and system are provided for visualizing and analyzing spectrum assets. License, channel, and lease data from a communications authority is collected and formatted into individual polygon maps. The maps could be drawn according to county or state boundaries, or by some other mapping standard. The maps are then divided and redrawn into several market service areas and several basic trading areas. The maps are also divided and redrawn according to the bandwidth spectrum of one or more channels. Since the maps are drawn with several different boundary conditions, the layout of all of the maps result in some maps being partially overlaid onto other maps for the same region. These regions containing partially overlaid maps are redefined as superblocks. Each superblock contains all of the data from each overlaid map portion for that particular region. These superblocks provide a means of displaying or representing a completely mapped region, such as the continental United States in a completely non-overlapping manner. Several methods analyze the newly formed non-overlapping data map for purposes of deriving current assets and forming future marketing strategies.
