mapdata (version 2.3.0)

world2Hires: 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.
