SDTS Workshop Results - Technical Session

Speaker: Oscar Franzese and Steve Gordon

Oak Ridge National Laboratories

Topic: A Transportation Profile with GDF Extensions

GDF information is available at: http://www.intergraph.com/ehq/gdf

Oak Ridge (ORNL) is also developing and seeking comments for an on-line collection of similar transportation data definitions and terms from several common data dictionaries and catalogs of features, attributes, and relationships, including some terms from the FHWA ITS data dictionary and the GDF catalogs. This information compiled by Oscar is at: http://itsdeployment.prg.utk.edu/definitions/
