About this app

Hazards and Population Mapper (HazPop) is a free app that enables users to easily display recent natural hazard data in relationship to population, major infrastructure, and satellite imagery. Hazards data include the location of active fires over the past 48 hours; earthquake alerts over the past seven days; and yesterday′s air pollution data measured from space. The app shows the location of major dams and nuclear power plants and provides more detailed information and imagery for these facilities where available. By drawing a circle around a point or area of interest on the map, users can obtain an estimate of the total population and land area enclosed within.

Developed by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by the Center for International Earth Science Information Network (CIESIN) at Columbia University, HazPop combines data and map layers from various sources including NASA's Global Imagery Browse Services (GIBS), the U.S. Geological Survey (USGS), and others using a variety of open Web mapping services. The custom population estimates are provided by the SEDAC Population Estimation Service (PES) based on SEDAC′s Gridded Population of the World, version 4 (GPWv4) data for 2015.

HazPop is designed to be used by disaster risk managers, humanitarian response organizations, public health professionals, journalists, and others needing a quick assessment of the potential dangers posed by a major hazardous event or developing emergency. For example, a disaster response agency can obtain a rough estimate of the population and major facilities near a recent earthquake as an input into response planning. Journalists or students can explore the location of recent wildfires relative to dense populations, roads, terrain, and water bodies. Due to the coarse resolution and varying quality of some of the data, HazPop is not intended to support in-depth risk assessment or location-specific response needs.
