    <dct:description>The Low Elevation Coastal Zone (LECZ) Urban-Rural Population and Land Area Estimates, Version 2 data
set consists of country-level estimates of urban population, rural population, total population and land area country-wide and in LECZs for
years 1990, 2000, 2010, and 2100. The LECZs were derived from Shuttle Radar Topography Mission (SRTM), 3 arc second (~90m) data which were
post processed by ISciences LLC to include only elevations less than 20m contiguous to coastlines; and to supplement SRTM data in northern
and southern latitudes. The population and land area statistics presented herein are summarized at the low coastal elevations of less than
or equal to 1m, 3m, 5m, 7m, 9m, 10m, 12m, and 20m. Additionally, estimates are provided for elevations &gt; 20m, and nationally. The spatial
coverage of this data set includes 202 of the 232 countries and statistical areas delineated in the Gridded Rural-Urban Mapping Project
version 1 (GRUMPv1) dataset. The 30 omitted areas were not included because they were landlocked, or otherwise lacked coastal features.
This data set makes use of the population inputs of GRUMPv1 allocated at 3 arc seconds to match the SRTM elevations, and at 30 arc seconds
resolution in order to reflect uncertainty levels in the product resulting from the interplay of input population data resolutions (based
on census units) and the elevation data.. Urban and rural areas are differentiated by the GRUMPv1 Urban Extents. See data set documentation
for specifics on the methodologies used. This data set is produced by the Columbia University Center for International Earth Science
Information Network (CIESIN).  (Suggested Usage: To provide estimates of urban and rural populations and land areas for the years 1990, 2000, and 2010; and projections to the year 2100 for 202 countries with contiguous coastal elevations in the following categories: less than or equal to 1m, 3m, 5m, 7m, 9m, 10m, 12m, or 20m; as well as national totals. )</dct:description>
