The Bureau of Transportation Statistics (BTS) has developed a Data Converter
(EXE-528KB) for use with the National Transportation
Atlas Data (NTAD) and North American Transportation Atlas Data (NORTAD). The
Data Converter run Windows 95/NT. The Data Converter reads NTAD and NORTAD data
files and converts it for use into several common Geographic Information Systems
(GIS) formats: ArcView, ARC/INFO generate, Caliper (TransCAD/GISPlus/Maptitude),
Intergraph, LandView and MapInfo. The Data Converter only converts the base
NTAD files; the attribute files must be linked separately from the GIS. Refer
to the metadata for each database to determine the key field that links the
attributes.
For users not having a GIS, BTS recommends downloading the LandView III software
from one of the following websites:
The mapping software in LandView III is an adaptation of Mapping Application
for Response, Planning, and Local Operational Tasks (MARPLOT), part of the Computer-Aided
Management of Emergency Operations (CAMEO) system. MARPLOT was developed by
the Hazardous Materials Response and Assessment Division of National Oceanic
and Atmospheric Administration. The database software LandView III was developed
at the EPA Chemical Emergency Preparedness and Prevention Office.
Landview III is free when downloaded from the Right to Know Network and is
available from Census for $99 per compact disc (CD). Each CD contains geographic
data from TIGER/Line 95. The Census website also includes technical documentation
and a tutorial.
