Monrovia, Liberia Human Geography Data Summary


Provided by DigitalGlobe, Inc. in cooperation with Esri and NGA.

DigitalGlobe Landscape +Human datasets are analyst-ready map layers that serve as a foundation for conducting geospatial analysis. The data conforms to the World-Wide Human Geography Data Working Group (WWHGD WG) efforts to provide a basis for a deeper understanding of cultures, activities, and attitudes. Such datasets are especially useful in supporting crisis situations, such as the Ebola virus outbreak, in parts of the world that tend to lack publicly available map data for use with GIS tools such as ArcGIS Online.

The dataset used for this exercise to evaluate possible locations for Ebola treatment clinics in Monrovia, Liberia contains the following layers:
