TRB/NCRST MidWest Tri-State DOT Technology Exchange Meeting
2001 August 14, Decorah IA
Three midwestern states associated with the Infrastructure consortium
met for a day in Decorah IA — their geographic centroid — to share experiences
in RS-T (current and new initiatives, success stories, barriers) and to
forge a common plan of action for the future in cooperation with NCRST.
The NCRST institutions outlined their research agenda (developed over the
past year with considerable DOT consultation), and the state DOTs reported
on their activities and plans. The group came up with general goals
and objectives, a list of institutional and research issues, and a plan for
moving forward through technical development and outreach.

TRB/NCRST would like to hold similar meetings in other regions, in the
U.S. and abroad, to empower DOTs at the local level with technical awareness
and cooperative initiatives.

- University of California, Santa Barbara — Val Noronha
Summary of Discussions
Goals, Objectives, Action Items
- Geographic data sharing
- Sharing performance specifications
- Inreach within organizations: developing documents and presentations
like MN's photogrammetry spread
- Develop a tri-state report for TRB RS-T meeting, December 2001,
- tri-state overview
- component reports from each state
These issues are probably pertinent to all DOTs nationwide, and may
be explored by TRB.
- Vendor contracting: some vendors show little enthusiasm for prospective
- Data ownership: vendors require that states buy multiple licenses
- Need for common specs (accuracy)
- Computer networks, hardware inadequate for RS data volumes
- Need for enterprise-wide coordination: data sharing between offices
in DOTs, technical agreement on specifications (e.g. this would streamline
the evolution of design drawings and as-built surveys into centerline databases
for asset management and numerous other applications).
Fodder for the NCRST research agenda
NCRST team en
route to Decorah, assisted by GPS
- Scientific documentation of LIDAR accuracy, and comparison with
photogrammetry for specific applications (e.g. cut and fill).
- Tools that blend LIDAR with photogrammetry
- Document typical deviations between plans and as-builts
Broaden participation in this group
Current (2001) applications: find new users for available information
Describe new (2005) vision and specific applications
Role of TAPs, private contractors
Develop partnerships: cities, counties, NSDI

Special thanks to Dave Gorg for taking the initiative to hold this meeting,
and to Mike Leegard for a great job on organizing it.
