Using GIS to Manage and Analyze a Landfill - by Mike Michels, Vice President, Aaron Weier, GIS Director GIS technology is essentially smart, computerized mapping that overlays a great deal of data on maps, providing a detailed, three-dimensional look at the geography of a landfill — “A place to put everything in one spot — you go to a map, click around, and find that information a lot more quickly.” Those three-dimensional maps also give managers clues where to place wells to monitor landfill water and gas flows, and where to drill to draw off landfill gas to burn for energy generation. Converting monitoring data to meaningful, clear maps with GIS helps landfill managers make better decisions faster. This presentation was originally presented by Cornerstone's Executive Vice President (Mike Michels) at the 25th annual Solid Waste Technical Conference at Michigan State University.
