Enhancing Homeland Security With LandScan USA Track: Homeland Security Author(s): Budhendra Bhaduri, Phillip Coleman, Edward Bright Natural and manmade disasters place our national infrastructure along with vast populations at risk, often with little or no warning. Accurate population counts are critical for emergency preparedness and response. Typically population data are reported by administrative or accounting unit and represent "residential" or "nighttime" population. The LandScan USA Population model developed at Oak Ridge National Laboratory offers an effective way to overcome this limitation by developing a very high-resolution population distribution data that depicts a more realistic non-uniform population distribution. LandScan USA utilizes GIS and Remote Sensing data and technologies through a dasymetric modeling approach.In addition, LandScan USA offers a daytime population distribution model since emergencies do not always occur at night. Moreover,integrating demographic and transportation models with LandScan USA allows unprecedented capability of estimating time-variant population dynamics which can greatly enhance the analytical capability for numerous homeland security applications including emergency preparedness and response.
