2004 UC Proceedings Abstract
 Welcome to BTS National Transportation Atlas Database (NTAD) Track: Metadata and Data Publishing Author(s): Raquel Wright, Patricia Solano, Steve Lewis The NTAD is a set of about 26 transportation-related geospatial datasets gathered, processed, documented, reviewed, and released by BTS. Data is gathered in different formats and loaded in ArcSDE. Attributes are scrubbed and validated and a series of spatial validation procedures are performed. FGDC compliant metadata is created explaining the source, methods, and contact information. BTS distributes the data as shapefiles through an annual CD released in the summer and is also available through a web-based download application available. This application is part of the "Mapping Center" located on the BTS' Web site that host transportation applications where the data can be displayed and downloaded (http://www.transtats.bts.gov/MappingCenter.asp). Data can be selected by an area of interest in an interactive viewer or by selecting the geographic area of interest in a pull down menu.
