The LandScanTM Dataset comprises a worldwide population database compiled on a 30" X 30" latitude/longitude grid. 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 information. LandScan has been developed as part of the Oak Ridge National Laboratory (ORNL) Global Population Project for estimating ambient populations at risk.

Global Cattle density (2005): The Gridded Livestock of the World FAO (2007). This dataset forms part of a global livestock mapping project by the Food and
Agriculture Organization's Animal Production and Health Division (FAO-AGA). Predicted global cattle density (2005), corrected for unsuitability, adjusted to
match FAOSTAT totals for the year 2005. Number per square km, spatial resolution of 3 arc minutes (approx. 5km).These data are freely available through the GLW website, through an interactive web
application known as the Global Livestock Production and Health Atlas (GLiPHA), and through
the FAO GeoNetwork data repository (see http://www.fao.org/AG/AGAInfo/resources/en/glw/GLW_dens.html)
