During the initial site visit we established semi permanent survey control before laser scanning the ochre pile and creating a meshed terrain surface. Once the material had been removed we returned for a second site visit and, using the original survey control established during visit 1, we repeated the exercise which resulted in a second terrain surface. We could then compare the two meshed surfaces and calculate a displacement volume (i.e. the volume of material moved).
Our client required this information to inform a report, detailing what volume of material had been moved. A volumetric survey is a simple, cost effective way of accurately detailing this kind of information and can be undertaken in a variety of ways depending on site conditions. In this case a cost-effective and safe solution was to calculate the volume from a point cloud.
