Great Lakes GIS
The Great Lakes GIS Project proposes to provide comprehensive GIS projects for each Great Lake and the entire Great Lakes basin and provide recommendations for long-term distribution and maintenance of GIS-based data.
Cornell University Geospatial Information Repository (CUGIR)
CUGIR is an active online repository in the National Spatial Data Infrastructure program. CUGIR provides geospatial data and metadata for New York State, with special emphasis on those natural features relevant to agriculture, ecology, natural resources, and human-environment interactions.
Penn State University
Digital Chart of the World Server
Download the boundaries and layers of different countries, in Arc/INFO export format, from ESRI's Digital Chart of the World data (VMap Level 0 Version 001, 1993).
Montana State University
Environmental Statistics Group
The Environmental Statistics Group maintains several national datasets relating to waterways (including Hydrologic Unit Codes).
National Imagery and Mapping Agency
U.S. Imagery and Maps
National Imagery and Mapping Agency (NIMA) has developed a standard digital dataset (Digital Terrain Elevation Data (DTED®) Level 0) as well as other datasets. DTED® Level 0 elevation post spacing is 30 arc second (nominally one kilometer).
National Oceanic and Atmospheric Administration
National Geodetic Survey
The National Geodetic Survey site maintains numerous sets of data related to surveying and navigation.
The NOAAServer gives access to distributed NOAA data and information.
The NOS MapFinder service provides "one stop shopping" for images and data from a number of National Ocean Service (NOS) offices. The cornerstone of NOS MapFinder is a robust set of products available directly from the Web. These products are offered by theme (e.g., coastal aerial photography, low resolution nautical charts, coastal survey maps, etc.) Products are accessed through a spatial inventory that locates and describes all data that NOS possesses for each theme.
Great Lakes Environmental Research Laboratory
GLERL Data Library
The Great Lakes Environmental Research Laboratory's (GLERL) data library with topics including bathymetry, biologic, historic, and real-time data.
Natural Resources Canada
Canada's access to geographical data.
The Atlas of Canada
National Atlas data provide coverage of all of Canada. Data elements are feature coded and structurally clean. Base map components are available in five scales and a number of data exchange formats.
U.S. Fish and Wildlife Service
National Wetlands Inventory
Download National Wetlands Inventory (NWI) datasets related to the Nation's wetlands and deepwater habitats.
National Wildlife Refuges
Primarily maintaining data for Region 5 of the U.S. Fish and Wildlife Service (FWS), this site maintains datasets for National Wildlife Refuges and some other datasets created by FWS and USGS.
U.S. Fish and Wildlife Service Spatial Data Sources
This site maintains the U.S. Fish and Wildlife Service's links to most of its GIS datasets.
U.S. Geological Survey
USGS Geography (formerly Mapping) provides scientific information to describe and interpret America's landscape by mapping the terrain, monitoring changes over time, and analyzing how and why these changes have occurred.
National Atlas of the United States
This site maintains a diverse collection of data that can be accessed in a variety of ways. Datasets can be viewed as printed maps, through an interactive online browser, as animated multimedia maps, or as downloadable files.
Upper Midwest Environmental Sciences Center
A wide array of datasets and applications from the USGS for the upper Midwest region.
