Measles counts were obtained from the public SurvStat database of the
Robert Koch institute: http://www3.rki.de/SurvStat. A shapefile of Germany's districts as of 01/01/2009 was obtained from
the Service Center (www.geodatenzentrum.de) of the German
Federal Agency for Cartography and Geodesy (www.bkg.bund.de).
The map of the 17 districts of the Weser-Ems region
(measlesWeserEms@map
) is a simplified subset of this
shapefile using a 30% reduction via the Douglas-Peucker reduction method
as implemented at MapShaper.org.
