Illinois, Chris Pearson

Height Modernization in Illinois• Significant progress has been made in establishing

a height modernization program in Illinois– Identified a state agency willing to take the lead– Established a coordinating council of

representatives from state agencies (IDOT, IDNR, ISGS and the state water survey)

– Developed a draft statement of need– Presentations to members of the state political

establishment– Identified a member of the Illinois congressional

delegation who has offered to support the program

Illinois, Chris Pearson Other activities• Project submission

– Numerous projects for IDOT– Commemorative marks

• National adjustment– Series of seminars for universities in the Midwest

• Purdue and UW so far– SLIS Paper

• Regular lectures in Geodesy and GPS for Illinois Universities– UIUC, SIU and NIU– Parkland Community College, ICCC, Rend Lake Community

College• Short courses on GPS and Least square adjustments IPLSA annual

meeting• Short course on “Geodesy for geographers” for ILGISA• Short course on PAGES processing for NCAT

Ohio, Dave ConnerGreat Lakes ProjectMore than an NGS project...

• One of the largest cooperative GPS projectsever undertaken by NOS• Organized under the auspices of theInternational Joint Commission'sGreat Lakes Coordinating Committee• Designed to maintain accurate height relationshipsbetween U.S. and Canadian water level gauges,the International Great Lakes Datum (IGLD85) and the NAVD88• Spans 8 states and 2 Canadian provinces• 34 receivers on the US side, about 8 in Canada• U.S. observers include 11 from NGS (including five Advisors),2 private sector volunteers (organized thru State Advisor contacts)and the rest made up of State Agency volunteers.

Ohio DOT CORS Network

• 51 stations

• Nation’s first statewide RTK GPS Infrastructure

• Statewide VRS capability

• Planning is underway to run levels to ARP of all ODOT CORS
