This database produces a high-resolution map of New Zealand. The
database includes Pacific and sub-antartic island dependencies also.
Format
The data file is merely an assignment to a character string which
specifies the name of an environment variable which contains the
base location of the binary files used by the map drawing functions.
This environment variable (R_MAPDATA_DATA_DIR for the datasets in the
mapdata package) is set at package load time.
