FY 2015 Accomplishments

The subcommittee’s accomplishments for 2015 include the following:

  • In April 2015, USDOT hosted the National Address Database Summit.
  • The NGDA Dataset Manager for the railroad network focused on a major update to this dataset, which is conflating the Federal Railroad Administration rail network with data that was developed by NGA. The final product, the North American Rail Network, is planned to be completed in October 2015, and will be the primary rail network for all of the Federal Government and the rail industry.
  • The USDOT registered the Transportation Theme’s NGDA Datasets in the and catalog. The Theme Lead supported the implementation of the NGDA Management Plan by working with Dataset Manager and coordinated baseline NGDA Dataset lifecycle maturity assessments.
  • The USDOT implemented its policies for metadata, procedures, and guidelines for using the clearinghouse, developing transportation data standards, and creating a geospatial strategic plan for USDOT.
  • The second annual submission of the All Roads Network of Linear Referenced Data (ARNOLD) was received. Of the 52 submissions (one from each State Department of Transportation, plus from the District of Columbia and Puerto Rico), 38 were able to meet the new “all roads” requirement, 10 were slightly lacking, and 4 are in need of assistance.
