Parent Layer: Wildfire Effects and Values Impacted

Name: Where People Live

Display Field: VALUE

Type: Raster Layer

Geometry Type: null

Description: Where People Live (WPL) represent housing density per 30 sq meters. This dataset was developed for the West Wide Wildfire Risk Assessment (WWA) project. The Where People Live data set was developed using advanced modeling techniques based on the LandScan population count data available from the Department of Homeland Security, HSIP Freedom Data Set. The HSIP Freedom data set was available at no cost to U.S. local, state, territorial, tribal and Federal government agencies. See the following: (http://www.dhs.gov/files/programs/gc_1156888108137.shtm). Developed by the Oak Ridge National Laboratory, LandScan has been developed using sophisticated algorithms that integrate high-resolution imagery, nighttime lights imagery, and other local spatial data to identify daytime and nighttime population distributions. The Oak Ridge National Laboratory LandScan web site has a more detailed description of the data set at http://www.ornl.gov/sci/landscan/. Note the Where People Live data layer includes categories up to greater than three housing units per acre or greater, one housing unit on 1/3rd of an acre. This, in many cases, includes dense urban areas.
