Tobler's pycnophylactic population density
The source data was projected using Arc/Info into the required resolution,
the view above displays the classified density.
Source=Tobler's smooth pycnophylactically
interpolated population density surface.
This layer is quite a smooth approximation of population density and could
be an extremely useful intermediary population density layer for finding
patterns between Nuts3 and 1DM resolution population density.
