Mr. Banschbach is an Indiana licensed land surveyor with 19 years of experience in the profession. He is currently the Manager of the Indiana Department of Transportation’s Office of Aerial Engineering (OAE). OAE is responsible for the construction, administration and management of the InCORS Network. InCORS is a network of DOT owned and operated continuously operating reference stations, which provides statewide coverage for static and real time GNSS (GPS & GLONASS) positioning, based on a grid of stationary receivers installed at sufficient density to provide network corrections. Eric is part of the Indiana Height Modernization Committee, in addition to representing Indiana on the Great Lakes Region Height Modernization Program Consortium.
William Henning
Mr. Henning is a Registered Professional Land Surveyor with over 41 years of active experience in all phases of surveying technology. He has helped plan, construct, process, adjust and manage height modernization geodetic networks for county-wide projects in the U.S. He has been actively involved with education/outreach to the geospatial community for almost 20 years, presenting over 60 talks and workshops on surveying and GNSS technology. He has 15 years experience working with various GNSS manufacturers’ real time positioning systems. Mr. Henning is a Past President of the American Association for Geodetic Surveying (AAGS) and is an ACSM/AAGS Fellow. He is currently employed by NOAA’s National Geodetic Survey (NGS as a Senior Geodesist, where he is helping to develop guidelines and support methodology for real time positioning with state, national and international organizations.
Chris Pearson
Mr. Pearson works for the National Geodetic Survey where he is the geodetic advisor for Illinois. He lives in Springfield where he works with the Illinois Department of Transportation to maintain and improve geodetic control in Illinois. He was instrumental in establishing Illinois's Height Mod program. He gives numerous short courses and guest lecturers in Illinois and surrounding states. He is also responsible for maintaining the model of crustal deformation that NGS uses to correct coordinates and survey data for tectonic motion in the western US. Chris has a PhD from the University of Otago in New Zealand where his PhD concerned the measure ment of crustal deformation on the New Zealand plate boundary. He also has been a post doctoral researcher in Columbia University and the University of Otago working in crustal dynamics.
Renee Shields
Ms. Shields is a geodesist in the Geodetic Services Division of the National Geodetic Survey (NGS). She received a bachelor’s degree in Mathematics from the University of Massachusetts/Boston in 1976. Ms. Shields has been with NGS since 1980, and has experiÂenced major involvement in the geodetic adjustÂments for the North American Datum of 1983, and integration of new Global Positioning System (GPS) projects into the National Spatial Reference System (NSRS). This included assisting in the development of the constrained adjustment guidelines, primary responsibility for the High Accuracy Reference Networks adjustÂments, and the state-wide readjustment of several states. She has extensive experience in GPS and Geoid Height analysis, and has successfully used this experience to develop and conduct workshops around the country on incorporation of data into the NSRS. Renee is currently Project Manager for the Height ModÂernization Program, an effort that has 17 states as regular participants and additional activities in a number of other states. She coordinates and manages the program, through outreach activiÂties, education, and development of policies and guidelines, with the goal of establishing nationÂwide implementation of Height Modernization.
Boudewijn H.W. van Gelder
Since 1995 Dr. van Gelder has served as the State of Indiana Geodetic Advisor. He is a professor of Land Surveying and Geomatics Engineering within the School of Civil Engineering at Purdue University, and has taught there since 1992. His Masters of Science in Geodetic Engineering is from the Delft University of Technology and his Ph.D. is from The Ohio State University. Previously, he taught Geodetic Engineering at Delft. Dr. van Gelder teaches or has taught courses in a vast variety of geomatics courses including physical, satellite and geometric geodesy. He is a member of ACSM, the Indiana Society of Professional Land Surveyors, AGU, and others. He is also a member of one of the committees on Geophysics of the Royal Netherlands' Academy of Arts and Sciences (KNAW). From 2000 to 2002 he represented the Netherlands in the Education Committee of FIG.
