Spatial Data & GIS
Taking a spatial perspective on your research may help you ask and answer new questions. Spatial data can be challenging to interpret if you have not worked with it before. For assistance with spatial analysis and mapping, visits Data@Reed.
Thousands of geospatial data layers available through a single interface. Data types include US census; elevation; transportation; hydrography; administrative boundaries; land use; demographics; topographic maps; satellite imagery; and aerial photography.
An implementation of OpenGeoPortal - a partnership between several of the country's leading universities and a state agency. Partners include Tufts, Harvard, MIT, Princeton, MassGIS, Stanford and UC Berkeley.
