Thursday, July 31, 1997 -- The U.S. Secretary of Transportation
Rodney E. Slater today announced the release of the National
Transportation Atlas Databases--1997 (NTAD97) from the
departments Bureau of Transportation Statistics (BTS).
BTS Director Dr. T. R. Lakshmanan said,
"These databases provide a foundation for the transportation
layer of the National Spatial Data Infrastructure (NSDI). We plan
to work closely with state and local governments to enhance,
update, and maintain these databases."
NTAD97 is a set of national geographic
databases of transportation facilities. These databases include
geospatial information for transportation modal networks and
intermodal terminals, and related attribute information. Each
database includes documentation according to the metadata content
standards as prescribed by the Federal Geographic Data Committee
(FGDC).
This is the third release of the atlas.
The 1997 version includes updated geography and attribute files
in a standard ASCII text format. The data on the CD-ROM support
research, analysis, and decision- making across all modes of
transportation. The databases are most useful at the national
level, but have major implications at the regional, state, and
local scale throughout the transportation community.
This CD-ROM provides transportation
planners and researchers geographic and attribute information for
22 datasets. These datasets include Public Use Airports, Amtrak
Stations, Water Ports, the National Highway Planning Network,
National Railway Network, Fixed Guideway Transit Network plus
High Occupancy Vehicle Roadways, State Boundaries with Integrated
Shoreline, Federally Adjusted Urbanized Areas, the Bureau of
Economic Analysis Economic Areas, and more.
NTAD97 is available in both DOS/Windows
and UNIX compatible CD-ROM format. The databases are designed for
use within a Geographic Information System (GIS). To allow those
without a GIS to view the data graphically, BTS is releasing a
Windows NT/95 based data viewer. For those with a GIS, the data
viewer will convert the geospatial data to a number of popular
GIS formats. The data viewer is available through the Internet at
http://www.bts.gov/gis/ntatlas/translation.html.
