How to calculate contour lines

3Dsurvey software combines thousands of aerial drone imagery to provide the ultimate mining surveying tool.

Compared to traditional technology that is labour- and cost intensive, drone-based mapping of open-pit mines, quarries and pits by generating point clouds, DSMs and orthophotos adds to safety, cost-efficiency and accuracy.

3Dsurvey has an extremely useful, fast and precise tool that empowers you to generate and calculate contour lines in seconds.
