National Atlas Delivers New Million-Scale Digital Map Data

What's "1"? It’s the new set of digital cartographic frameworks from The
National Atlas of the United States of America <http://nationalatlas.gov/>.
Prepared at one million-scale (where an inch on a map is nearly 16 miles)
this authoritative and integrated national dataset has twice the detail of
previous versions. Users can now easily find “one” using popular search
engines or portals like Data.Gov; get it as documented data or Web map
services from nationalatlas.gov and other sources; and use "one" in their
geospatial analyses, maps, or map mashups.

This is the first time the Federal government has ever released these basic
digital map themes at 1:1,000,000-scale:

• Boundaries (national, state, and county)
• Transportation (roads, railroad, railroad stations, airports, and
• Surface waters (coastlines, streams, gaging stations, waterbodies,
and wetlands, all fully networked)
• Cities and towns

This new release serves as the foundation for small-scale maps and datasets
on the Nation's people, heritage, and resources. The new map data is
delivered at no cost and is available on-line <http://nationalatlas.gov/> as
a web map service from nationalatlas.gov "For more than 130 years the USGS
has been the 'go to' source for quality maps and authoritative map content,"
said USGS Director Marcia McNutt. "The new million-scale digital series
continues this proud tradition, providing users with multi-million uses only
limited by their imaginations."

By moving to one million-scale, the National Atlas achieves two goals to
better serve national and international audiences. First, map features have
been harmonized at the U.S. borders of Canada and Mexico with data from
national mapping programs in those nations for use in the Environmental Atlas
of North America <http://www.cec.org/atlas>. Also, a second edition of the
data that conforms to the specifications of the Global Map
<http://www.iscgm.org/> is ready. Global Map is an international effort by
government mapping organizations to make a consistent map of the world at one
million-scale Future releases are scheduled to include: Federal and Native
American lands, Congressional Districts, U.S. Statistical areas and more.

The National Atlas of the United States® is a cooperative effort to make
geographic information collected by the United States government easier to
find, get, and use. Its development is led by the U.S. Geological Survey.
