The document reports the results of a questionnaire given to various federal agencies regarding their geospatial transportation data needs. Most agencies cited a lack of current, complete, and accurate public domain data as a key issue. Common data sources included Census Bureau, state and local governments. Many applications require features like roads, bridges, and railroads. Attributes like names and routing were also important. However, needs varied between agencies, especially regarding update frequency, accuracy standards, and whether certain attributes should be public.
