Urban & Environmental Modeler’s Datakit
The Urban & Environmental Footprint 2050 Project at the Institute of Urban and Regional Development (IURD) at UC, Berkeley have constructed a GIS toolkit consisting of a series of ESRI shapefiles and grids describing, “many of the physical, administrative, transportation, demographic, economic, land use and land cover, and environmental characteristics of the 48 contiguous United States.” The data were pulled together by the Penn Institute for Urban Research and and the IURD. Layers include boundary files, census block files and attributes, transportation networks, major employment center information, measures of job accessibility, boundaries of federal lands, elevation and slope data, location of water bodies, and location of wetlands. The data are free and can be used for any purpose with attribution. A great new, free resource!
