Trash k l ta speaks volumes Landfill operations use geospatial services to help with crucial measurements – and the bottom line By Jason Sweet A bird’s-eye view of a landfill site may not reveal how much it’s the result of careful measurement and planning. But it is. It has to be. Landfill operators want their facilities to function safely and efficiently – and profitably – as they adhere to regulations. To do this requires constant monitoring and frequent measuring of landfill data. Calculating volume may invoke math class memories for some, but for landfill operators, it’s way more than a mathematical exercise. Volumetric landfill quantities are possibly the most useful data they have for planning facilities wisely, operating efficiently, and maintaining financial viability. So 2│ TRENDS how does one go about measuring the volume of a landfill? It’s back to that bird’s-eye view for starters. Ayres Associates provides geospatial services for landfills around the country. Cornerstone Environmental Group recently worked with Ayres Associates to provide geospatial services for 21 active landfill sites in seven states. Using its Leica digital aerial camera from a Cessna aircraft, Ayres Associates acquired aerial imagery and then created 2-foot interval topographic contours of the active sites.
