U.S. Army CRREL Ron Liston Seminar: ISTVS 7th Americas Conference

7th Americas Regional Conference of the International Society of Terrain-Vehicle Systems

Timothy Cary and Heidi Howard

Cold Regions Research and Engineering Laboratory

Construction Engineering Research Laboratory

Innovative solutions for a safer, better world

Conference Venue

Tampa Florida November 4 – 7 2013 Combined with: American Society of Agronomy (ASA) Crop Science Society of America (CSSA) Soil Science Society of America (SSSA) Canadian Society of Agronomy (CSA)


ISTVS Mission To advance knowledge into terrain-vehicle (machine) systems for improvements in engineering practice and for innovation in the terrain-vehicle domain. ISTVS promotes the transfer of advanced knowledge to the user for the benefit of society at large in environmental protection, energy conservation, and sustainable development.


ISTVS Focus 7th Regional Americas Conference was focused on highlighting ERDC, NASA, and TARDEC research efforts. 2009 started development of combined ASA-CSSA-SSSA and ISTVS special session. Significant investment in the combined conference.
