Quarry calculations – calculating the volume of excavation and of levelling compounds

Virtual laser scanning is a technology that we have developed to enable efficient and precise orthophotography of quarry maps, digital terrain models, mining maps, vertical profiles and terraces of the quarry, topographic maps and quarry volume calculations. The area of several hectares was measured in two 25-minute flights; the data (photographs and ground control points) was then processed using 3Dsurvey.
