(2004): Development and validation of a global database of lakes, reservoirs and wetlands. Journal of Hydrology 296/1-4: 1-22. http://www.wwfus.org/science/data.cfm glwd_2 Level 2 of the Global Lakes and Wetlands Database (GLWD) comprises the shoreline polygons of permanent open water bodies with a surface area >= 0.1 square km, excluding the water bodies contained in GLWD-1. GLWD-2, together with GLWD-1, represents a global polygon map of lakes to which existing lake registers, compilations or remote sensing data can be linked and georeferenced. Supplemented by GLWD-1 and GLWD-3. en July 2004 Based on various data sources, mostly 1970s to 1990s.
