National
Parks Service - Since 1995, the focus of GIS in the National Park Service
has been on cartographic data acquisition for parks, GIS training, and technical
and administrative support for the growing number of GIS and GPS (Global Positioning
System) operations in parks. More than 250 National Park System units use
GIS today. Click on "GIS Data and Metadata" and select a state.
Chicago

DATA
Repository-
The UW-Madison Library GIS Data Repository emphasizes on-line data and metadata
for data sets of local interest and some specific licensed data sets. The
repository does not mirror or otherwise directly link to data sets which which
may be held by federal and other agencies. Please examine GIS Data Sources
for links to other data repositories and Clearinghouses.
Digital Orthophot
USGS NED Shaded
Relief Imagery Data - GIS users can download USGS NED Shaded Relief Imagery
Data to use in GIS software. With GIS software, you can use the data for geographic
reference or for a background image. You can also use it to enhance topographic
structure that is perpendicular to the illumination angle.
USGS Seamless Data Distribution
System, National Center for Earth Resources
Observation and Science (EROS). The Seamless Data Distribution System (SDDS)
is the ultimate location to explore and retrieve data. U.S. Geological Survey
(USGS) and the EROS Data Center (EDC) are committed to providing access to
geospatial data through The National Map. An approach is to provide free downloads
of national base layers, as well as other geospatial data layers.
