Description:
The USGS node of the National Geospatial Data Clearinghouse provides
a pathway to find information about geospatial or spatially referenced
data available from USGS, including: biological resources, water
resources, geologic information, remotely sensed data, and National
Mapping Program information.
Formats:
The information is in the form of metadata. Metadata, or "data about
the data", describe the content, quality, condition, and other characteristics
of data. Data available include DEMs, DLGs, raster data…

Description:
Access to easy-to-use, digital map-like views of America's natural
and socio-cultural landscapes, particularly the environmental, resource,
demographic, economic, social, political, and historical dimensions
of American life. The Atlas is a 1997 update of a large bound collection
of paper maps that was published in 1970.
Formats:
Map layers are available in Shapefile (.shp) format and in the Topological
Vector Profile (.tvp) of the Spatial Data Transfer Standard. Image
files are available in the tagged image file format (TIFF). Data
tables are distributed in the DBF format.
Data
Access: All map layers can be downloaded at no cost using
file transfer protocol, but some are available for a small fee (less
