MidWest Regional Workshop on Remote Sensing in Transportation

2003 April 15, Madison WI

Workshop in progress

Mike Leegard presents, Ohio DOT (on screen) participates remotely

The University of Wisconsin organized a gathering of six midwestern states: Indiana, Iowa, Michican, Minnesota, Ohio and Wisconsin. The focus of this meeting was technology transfer of state DOT and research experiences with satellite, airborne and land-based remote sensing and digital photogrammetric technologies for transportation infrastructure projects. Goals for this meeting included encouraging dialog among Midwest state DOTs on experiences with these technologies, and identifying research needs in response to state DOTs experiences, thereby empowering Midwest state DOTs with technical awareness and cooperative initiatives on remote sensing and digital photogrammetry.

This meeting was partly a follow-up to the 2001 tri-state meeting in Decorah IA, at which state DOT photogrammetry staff shared experiences and expressed their priorities for NCRST research. The consortium has addressed those research issues in the interim period, and this meeting was a chance to report back to the states.

The meeting was broadcast by live streaming video to those who could not be present in Madison.

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.

Summary of Discussions

DOTs require help with

(a) accuracy assessment in corridors,
(b) analytical triangulation
(c) SRTM data for digital orthophotos: accuracy assessment and potential uses in corridor planning

NCRST research addresses these types of issues (and others identified in Decorah), up to a point. While DOTs consider this research valuable, DOTs require more formal statements and certifications. Such specialized outputs are not the role of NCRST; partnerships with private sector may be the only way to produce them.


Special thanks to Nick Koncz for a great job organizing the meeting.
