Illinois Height Modernization Program Workshop
The Illinois Height Modernization Program teamed up with the Illinois Department of Transportation to present a formal workshop at the Illinois Public Land Surveyors Meeting in Springfield, Illinois, February 15-18, 2012. Well over 200 professional land surveyors attended this workshop, which provided 2 Professional Development Hours to each attendee. Presenters included Amy Eller, P.E., Engineer of Aerial Surveys, IDOT; Sheena Beaverson, GISP, Principal Investigator, Illinois Height Modernization Program, Illinois State Geological Survey; and Michael Blumhoff, PLS, Level Manager for Illinois Height Modernization, Illinois State Geological Survey. The purpose of the Illinois Height Modernization Program is to (1) improve elevation information for Illinois by installing new surveying benchmarks to replace those destroyed or to increase the density of the network, and (2) acquire and distribute high-resolution elevation LiDAR data. Learn about on-going project activities and see a demonstration of DS World, free software from the National Geodetic Survey, which displays control points by state, county, and vertical or horizontal type in Google Earth. Learn how to use DS World to recover data from the NGS database and to make a report on the condition of a monument.
