Dataset Description
A digital elevation model (DEM) has been used to produce a topographic map for each country in the Atlas. The DEM is derived from the USGS Global 30 Arc-Second Elevation dataset (GTOPO30).

Capital cities shown in the Atlas are taken from the 2011 Revision of World Urbanization Prospects, provided by the United Nations Department of Economic and Social Affairs (Population Division, Population Estimates and Projections Section).
