Mapping Tools

The Hazards and Population Mapper (HazPop) is a free mobile application that enables users to easily display recent natural hazard data in relationship to population, major infrastructure, and satellite imagery. Users can visualize 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, and can estimate the total population in proximity to the user′s current location or to a recent hazard event or other point of interest. HazPop is designed for use by disaster risk managers, humanitarian response organizations, public health professionals, journalists, and others needing a quick assessment of the population potentially exposed to a major hazard event or developing emergency. It is not intended to support in-depth risk assessment or estimation of actual disaster losses. 

The SEDAC Hazards Mapper enables users to visualize data and map layers related to Socioeconomic, Infrastructure, Natural Disasters, and Environment and analyze potential impacts and exposure. The web app mashups layers from various sources including SEDAC, NASA LANCE, NASA GIBS, USGS, NOAA, ESRI, and others.

The Population Estimation Service (PES) is a Web-based service that lets users of a wide variety of map clients and tools  quickly obtain estimates of the number of people residing in specific areas without having to download and analyze large amounts of spatial data. Now updated with data from the new Gridded Population of the World Version 4 data set, the PES also contains a new feature, the SEDAC Population Estimator Web App, that enables users to draw a polygon or circle around an area of interest to obtain an estimate of the 2015 population in that area.

The map client for the Sea Level Rise Impacts on Ramsar Wetlands of International Importance data set is a Web-based service for assessing the exposure to sea level rise of coastal wetlands designated as  Ramsar Wetlands of International Importance (Ramsar Sites).

A Web mapping tool that enables visualization of all SEDAC map layers, the SEDAC Map Viewer organizes the map layers into approximately 15 interdisciplinary topics (themes) that users can select. Users may also zoom into a region of interest using a selection list, in addition to typical pan and zoom options. This updated version of the SEDAC Map Viewer implements an innovative four-window map view to make it easier to compare data layers from SEDAC’s diverse data holdings. The viewer is developed using the Open Layers JavaScript library and uses the SEDAC Web Map Services (WMS) published in GeoServer.

The Columbia University Superfund Research Program “NPL Superfund Footprint: Site, Population, and Environmental Characteristics” Mapper was created to provide researchers, regulators, and the general public with an innovative tool to better visualize and understand the characteristics of vulnerable populations, built and natural features, and environmental exposures near the National Priorities List Superfund sites. Its purpose is to help improve the evaluation of Superfund sites and more effectively address related environmental health concerns.

The Climate and Health Analysis for Global Education Viewer (CHANGE Viewer) was built using NASA World Wind, an open source, 3-D geo-visualization tool. CHANGE Viewer allows the exploration of climate science, human, and socio-economic data sets made available through the Data Library.

This tool developed by NASA's EOSDIS allows you to interactively browse global satellite imagery within hours of it being acquired. Users can overlay and visualize a subset of SEDAC map layers in conjunction with satellite images - for example, the NASA MODIS imagery showing active fires, integrated with the SEDAC GRUMP population density layer.
