- To provide estimates of urban and rural populations and land areas in the low elevation coastal zone.
- The Low Elevation Coastal Zone (LECZ) Urban-Rural Estimates consists of country-level estimates of urban, rural and total population and land area country-wide and in the LECZ, if applicable. Additionally, the data set provides the number of urban extents, their population and land area that intersect the LECZ, by city-size population classifications of <100,000, 100,000 to 500,000, 500,000 to 1,000,000, 1,000,000 to 5,000,000, and 5,000,000 +. All estimates are based on GRUMP alpha data products. The LECZ was generated using SRTM Digital Elevation Model data and includes all land area that is contiguous with the coast and 10 meters or less in elevation. All grids used for population, land area, urban mask, and LECZ were of 1 km (30 arc-second) resolution. This data set is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with the International Institute for Environment and Development (IIED).
