Ohio, Dave Conner Great Lakes Project More than an NGS project... One of the largest cooperative GPS projects ever undertaken by NOS Organized under the auspices of the International Joint Commission's Great Lakes Coordinating Committee Designed to maintain accurate height relationships between 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.
