The dams were geospatially referenced and assigned to polygons depicting reservoir outlines at high spatial resolution. Dams have multiple attributes, such as name of the dam and impounded river, primary use, nearest city, height, area and volume of reservoir, and year of construction (or commissioning). While the main focus was to include all dams associated with reservoirs that have a storage capacity of more than 0.1 cubic kilometers, many smaller dams and reservoirs were added where data were available. The data were compiled by Lehner et al. (2011) and are distributed by the Global Water System Project (GWSP) and by the Columbia University Center for International Earth Science Information Network (CIESIN). For details please refer to the Technical Documentation which is provided with the data.</abstract> <purpose>To provide a geographically explicit and reliable database of dams for the scientific community.</purpose> <supplinf /> </descript> <timeperd> <timeinfo> <sngdate> <caldate>2011</caldate> <time /> </sngdate> </timeinfo> <current>publication date</current> </timeperd> <status> <progress>Complete</progress> <update>As needed</update> </status> <spdom> <descgeog /> <bounding> <westbc>-153.027083</westbc> <eastbc>176.815417</eastbc> <northbc>70.387083</northbc> <southbc>-45.879583</southbc> <boundalt> <altmin /> <almax /> <altunits /> </boundalt> </bounding> <dsgpoly> <dsgpolyo> <gring /> </dsgpolyo> <dsgpolyx> <gring /> </dsgpolyx> </dsgpoly> </spdom> <keywords> <theme> <themekt>CIESIN Indexing Vocabulary Version 2.1 (GCMD Format)</themekt> <themekey>CIESIN > Environmental Protection > Water Forms > Reservoirs</themekey> </theme> <theme> <themekt>GCMD Parameter Valids</themekt> <themekey>EARTH SCIENCE > Human Dimensions > Environmental Impacts > Water Management</themekey> </theme> <theme> <themekt>General</themekt> <themekey>Dams</themekey> <themekey>Reservoirs</themekey> </theme> <theme> <themekt>EI Gateway Vocabulary</themekt> <themekey>Hydrology</themekey> </theme> <theme> <themekt>Data Granularity</themekt> <themekey>Continent</themekey> <themekey>Global</themekey> </theme> <theme> <themekt>ISO Topic</themekt> <themekey>Inland Waters</themekey> </theme> <theme> <themekt>WDC Theme</themekt> <themekey>Poverty</themekey> </theme> <theme> <themekt>CSA-NBII Biocomplexity</themekt> <themekey>Dams</themekey> <themekey>Reservoirs</themekey> </theme> <place> <placekt>CIESIN Location Terms, version 2.0</placekt> <placekey>Continent > Africa</placekey> <placekey>Continent > Asia</placekey> <placekey>Region > Equatorial</placekey> <placekey>Continent > Europe</placekey> <placekey>Global</placekey> <placekey>Region > Mid-Latitude</placekey> <placekey>Continent > North America</placekey> <placekey>Region > Oceania</placekey> <placekey>Region > Polar</placekey> <placekey>Continent > South America</placekey> </place> <stratum> <stratkt /> <stratkey /> </stratum> <temporal> <tempkt /> <tempkey /> </temporal> </keywords> <taxonomy> <keywtax> <taxonkt /> <taxonkey /> </keywtax> <taxonsys> <classsys> <classcit> <citeinfo> <origin /> <pubdate /> <pubtime /> <title /> <edition /> <geoform /> <serinfo> <sername /> <issue /> </serinfo> <pubinfo> <pubplace /> <publish /> </pubinfo> <othercit /> <onlink /> <lworkcit /> </citeinfo> </classcit> <classmod /> </classsys> <idref> <citeinfo> <origin /> <pubdate /> <pubtime /> <title /> <edition /> <geoform /> <serinfo> <sername /> <issue /> </serinfo> <pubinfo> <pubplace /> <publish /> </pubinfo> <othercit /> <onlink /> <lworkcit /> </citeinfo> </idref> <ider> <cntinfo> <cntperp> <cntper /> <cntorg /> </cntperp> <cntpos /> <cntaddr> <addrtype /> <address /> <city /> <state /> <postal /> <country /> </cntaddr> <cntvoice /> <cnttdd /> <cntfax /> <cntemail /> <hours /> <cntinst /> </cntinfo> </ider> <taxonpro /> <taxoncom /> <vouchers> <specimen /> <reposit> <cntinfo> <cntperp> <cntper /> <cntorg /> </cntperp> <cntpos /> <cntaddr> <addrtype /> <address /> <city /> <state /> <postal /> <country /> </cntaddr> <cntvoice /> <cnttdd /> <cntfax /> <cntemail /> <hours /> <cntinst /> </cntinfo> </reposit> </vouchers> </taxonsys> <taxongen /> <taxoncl> <taxonrn /> <taxonrv /> <common /> </taxoncl> </taxonomy> <accconst>None</accconst> <useconst>The Global Water System Project (GWSP) holds the copyright of this data set.
