LandScan is a global population database that shows geographical distribution of population at one-kilometer resolution over an average 24-hour period. Demographic (age, race, sex) and socioeconomic characteristics are integrated with population data to allow integration with risk and impact assessment models. 2011-2013.
LandScan is a unique data set showing population distribution, developed by the Department of Energy’s Oak Ridge National Laboratory (ORNL), and distributed by East View Information Services. The data represents ambient population (combined for night and day) at one-kilometer resolution. Details of age and gender are also provided at certain geographic scales. The data can be limited by state, country, region, or global level. A search can also be customized based on individually defined pixel points. Only the latest data is provided.
The information is derived from a combination of census data, algorithmic projections, and satellite imagery. The population calculations come from ORNL’s LandScan USA database (high resolution data derived at 3 arc-second ~90 meters), which is compiled for the Homeland Security Infrastructure Program (HSIP). High-resolution image sources include the National Geospatial-Intelligence Agency (NGA) Controlled Image Base (CIB). The data is displayed in GIS raster format (ESRI Grid). In 2011, East View obtained an exclusive license for all distribution of this database outside of internal government uses.
In the web application, selection of a specific geographic region results in graphic visualization of the population levels, in addition to charts representing population distribution by age and gender. Background views can be set to show topography, maps, or satellite imagery. Land cover features are shown, as well as buildings and other elements in more densely populated areas.
