3D Population Distribution in the Bay Area in 2000

This map depicts a multidimensional surface derived from population density distribution within the nine-county San Francisco Bay Area. A hillshade grid was layered beneath the grid depicting population density from which it was derived. In effect, this creates a shaded relief image of the Bay Area that is derived from population distribution rather than topography. As depicted in ArcScene, the inset maps show the same dataset, with heights obtained from the population field. A 0.25 factor was used to account for the extreme heights of these data values in relation to the size of the Bay Area landscape.
