lakes: World lakes database

World lakes database

Description

This database contains a selection of large lakes (and islands within) taken from the Natural Earth 1:50m map, the same data source as the (v3.0) world map. The lake boundaries are consistent with the 'world' database.

Usage

data(lakesMapEnv)

Format

The data file is merely 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_MAP_DATA_DIR for the datasets in the maps package) is set at package load time if it does not already exist. Hence setting the environment variable before loading the package can override the default location of the binary datasets.

Source

The data in this data base is derived from the public domain GIS project Natural Earth, the file "ne_50m_lakes". The Natural Earth data set is available from https://www.naturalearthdata.com.
