Shane McDermott, President of Mid-West GIS, Inc. of Quincy recently put on a presentation on River Gauge Markers and the Use of GIS and GPS to Battle Floods. The presentation was attended by local companies, representatives from local drainage districts, and representatives from the City of Quincy (including the Mayor). The presentation covered topics such as; using markers at critical locations on the levees and structures to determine crest heights, and using highly accurate GPS equipment (Survey Grade) to collect elevations to determine heights for protection along the levee system.
