Pacific Centric World Map
Description
This world database comes from a cleaned-up version of the CIA World Data Bank II data and contains approximately 2 million points representing the world coastlines and national boundaries. This map is based on latitudes [0, 360), which then has the Pacific Ocean in the centre of the map.
Usage
data(world2HiresMapEnv)
data(world2LoresMapEnv)
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.
Source
The CIA World Data Bank II is currently available from https://www.evl.uic.edu/pape/data/WDB/.
