Census counts (at sub-national level) were apportioned to each grid cell based on likelihood coefficients, which are based on proximity to roads, slope, land cover, nighttime lights, and other data sets. LandScan has been developed as part of the Oak Ridge National Laboratory (ORNL) Global Population Project for estimating ambient populations at risk. The LandScan files are available via the internet in ESRI grid format by continent and for the world. At approximately 1 km resolution (30" X 30"), There is also a "Layer" file (lspop2000.lyr) for ArcGIS. LandScan is the finest resolution global population distribution data available and represents an ambient population (average over 24 hours). This dataset is part of the LandScan 2000 Global Population Database (2000-2010).</abstract> <abstract lang="eng" displayLabel="Purpose">Developed for the U. S. Department of Defense. "The values of the cells are integer population counts representing an average, or ambient, population distribution. An ambient population integrates diurnal movements and collective travel habits into a single measure (Dobson et al. 2000). Since natural or man made emergencies may occur at any time of the day, the goal of the LandScan model is to develop a population distribution surface in totality, not just the locations of where people sleep. Because of this ambient nature, care should be taken with direct comparisons of LandScan data with other population distribution surfaces." --from the Oak Ridge National Laboratory LandScan Web site, Sept. 12, 2013.</abstract> <note lang="eng" displayLabel="Preferred citation">Oak Ridge National Laboratory.

Available at: http://purl.stanford.edu/sw496dr1185</note> <note displayLabel="Supplemental information">IMPORTANT: For correct population analysis using ESRI products assure that the following parameters are set: -Use ONLY Geographic, WGS84 projection parameters. -Spatial Analysis cell size is 0.008333333333333 (double precision) -Spatial Analysis extent should be set to an exact multiple of the cell size (for example 35.25, 35.50, 35.0) Converting (including on-the-fly projections) a grid to other projections or coordinate systems causes population cells to be re-sampled, and hence population counts will be incorrect. In ESRI ArcMap, load the LandScan grid first in order to maintain the original geographic (lat-lon) projection.</note> <subject authority="lcsh" lang="eng"> <topic authority="lcsh" authorityURI="http://id.loc.gov/authorities/subjects.html">Administrative and political divisions</topic> </subject> <subject authority="lcsh" lang="eng"> <topic authority="lcsh" authorityURI="http://id.loc.gov/authorities/subjects.html">Population</topic> </subject> <subject authority="geonames" lang="eng"> <geographic authority="geonames" authorityURI="http://www.geonames.org/ontology#" valueURI="http://sws.geonames.org/6295630/">Earth (Planet)</geographic> </subject> <subject> <temporal encoding="w3cdtf">2000</temporal> </subject> <subject authority="ISO19115TopicCategory"> <topic authority="ISO19115TopicCategory" authorityURI="http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml#MD_TopicCategoryCode" valueURI="imageryBaseMapsEarthCover">Imagery and Base Maps</topic> </subject> <subject authority="ISO19115TopicCategory"> <topic authority="ISO19115TopicCategory" authorityURI="http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml#MD_TopicCategoryCode" valueURI="society">Society</topic> </subject> <subject> <cartographics> <scale>Scale not given.</scale> <coordinates>W 180°--E 180°/N 84°--S 90°</coordinates> </cartographics> </subject> <subject displayLabel="WGS84" authority="EPSG" valueURI="http://opengis.net/def/crs/EPSG/0/4326"> <cartographics> <projection>EPSG::4326</projection> </cartographics> </subject> <originInfo> <dateIssued encoding="w3cdtf" keyDate="yes">2001</dateIssued> <place> <placeTerm type="text">Oak Ridge, TENNESSEE, US</placeTerm> </place> <publisher>Oak Ridge National Laboratory</publisher> <edition>2000</edition> </originInfo> <location> <url usage="primary display">https://purl.stanford.edu/sw496dr1185</url> </location> <recordInfo> <languageOfCataloging> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </languageOfCataloging> <recordContentSource>Stanford</recordContentSource> <recordOrigin>This record was translated from ISO 19139 to MODS v.3 using an xsl transformation.</recordOrigin> <recordIdentifier>edu.stanford.purl:sw496dr1185</recordIdentifier> </recordInfo> <extension displayLabel="geo"> <rdf:RDF xmlns:gml="http://www.opengis.net/gml/3.2/" xmlns:dc="http://purl.org/dc/elements/1.1/"> <rdf:Description rdf:about="http://purl.stanford.edu/sw496dr1185"> <dc:format>application/x-ogc-aig; format=ArcGRID</dc:format> <dc:type>Dataset#Raster</dc:type> <gml:boundedBy> <gml:Envelope gml:srsName="EPSG:4326"> <gml:lowerCorner>-180.0 -90.0</gml:lowerCorner> <gml:upperCorner>180.0 86.0</gml:upperCorner> </gml:Envelope> </gml:boundedBy> </rdf:Description> </rdf:RDF> </extension> <relatedItem type="host"> <titleInfo> <title>East View LandScan global population database</title> </titleInfo> <location> <url>https://purl.stanford.edu/zr161jq7891</url> </location> <typeOfResource collection="yes"/> </relatedItem> <accessCondition type="useAndReproduction">These data are licensed by Stanford Libraries and are available to Stanford University affiliates only.
