School Locations Point shapefiles and tabular data in Excel and SAS with address geocodes (estimated latitude/latitude values) and other geographic indicators to public schools, public local education agencies, private schools, and postsecondary schools.
eGRID (Emissions & Generation Resource Integrated Database): the PLNT (Plant) file includes longitude and latitude coordinates for nearly 10,000 generating plants in the US, as well as technical and emissions data for each.
Protected Areas Data (PAD-US)
Lands in PAD-US are mainly open space/resource lands owned by agencies and non-profits (all federal and most state conservation lands, and many areas at regional and local scales), as well as conservation easements suitable for distribution in the public domain, with information on how they are being managed for conservation purposes.
Elevation data, Digital Line Graphs (DLG), and land use (LULC) as vector layers
Land Use/Land Cover: Digitized from paper maps from 1970s-1980s, so should be used for historical studies. Each 1:250,000 scale LULC quadrangle covers 2º of longitude E-W and 1º of latitude N-S. WebGIS provides an index graphic that allows you to click on the counties or to choose from an alphabetical list. It will then list all 1:100,000 quadrangles that cover at least part of that county.
You will need to join a dBase file to the downloaded LULC layer's attribute table in order to match English words to the numeric LULC classification codes. (Field LUCODE in the attribute table matches to LU2-CODE in the dBase file.)
NASA (National Aeronautics and Space Administration)
Earthdata Lots of remote sensing data as well as support materials such as software tools. Use the DAAC drop-down to go to NASA's Distributed Active Archive Centers (DAACs), which are discipline-specific data archives.
National Renewable Energy Laboratory (NREL)
Data Resources: GIS data relating to renewable energy in the US (wind speeds, wave energy, solar potential). Some international data
Renewable Energy Data Explorer (REexplorer) Online mapping tool for visualizing energy-related map layers from selected non-US countries, most of which can be downloaded as GIS files.
NOAA nautical charts, bathymetry, and shoreline data
coastal change and analysis data: remotely sensed imagery and aerial photography (LiDAR and IfSAR data)
Benthic habitat maps, National Marine Sanctuaries boundaries and protected areas data
environmental sensitivity index maps; geodetic control benchmarks
coastal and marine observational data including real time tides and currents data for marine navigation.
NOAA Digital Coast Large repository of data and tools relating to coastal science and contributed by many partners. Includes 1024 data layers that relate to Lidar, land cover, economic data (continental shelf, EEZ, etc.), electronic navigational charts, imagery, and much more. Includes 53 tools (as of April 2014) to view or analyze such data. Includes some non-US data.
National Transportation Atlas Database
Online editions since 2011 for this set of databases, which include transportation facilities, transportation networks, and associated infrastructure. It includes attributes and metadata
